An officer at Air Force Space Command noticed that operators that were fatigued did not seem to perform as well as those operators that were well rested. He was interested if this observation was statistically significant and if added automation could help mitigate any negative effects of fatigue on monitoring and controlling satellites. He designed a study to look into this question. He recruited volunteers willing to participate in a sleep study. Participants would initially be restricted in sleep for a few nights, then would come in and perform tasks in a simulator that were representative of operational tasks. Participants would then be required to sleep 8 hours a night for a few nights, then would come in and perform the tasks in the simulator again. A sub-set of the simulator tasks were at a low level of automation and the remaining simulator tasks were at a high level of automation.a)[4 pts] What is/are the study independent variable(s)
Answer:
The independent variables are the level of tiredness and the number of hours slept by the volunteers.
Explanation:
Independent variables are those that act on the dependent variables influencing a result, which can be observed by the researcher. In summary, the independent variable is one that can influence. In the case of the question above, we can see that the number of hours slept by the volunteers influenced the level of tiredness of the volunteers. These two variables were able to influence the level of proactivity and performance of the volunteers in their activities, which allows us to determine that these two variables are the independent variables of the study.
Causes and consequences of Ukrainian war with Russia?
Answer:The Ukraine crisis is a power struggle between factions within Ukraine. One of the factions wants to align with the European Union and the other with Russia. As one of the founding states of the Soviet Union, Ukraine had been an important contributor to the Soviet Union's economy between 1920–1991On November 25, 2018, Russian ships attacked and boarded three Ukrainian vessels in the Crimean port of Azov near the Black Sea. It placed a freighter to block the port, stating that Ukraine had violated Russian waters, although the two sides signed an agreement in 2003 to guarantee free passage through the strait.4
Critics at the United Nations Security Council meeting said Russia's attack was a violation under international law. The North Atlantic Treaty Organization increased its military presence in the area.Putin's attack responded to the February 23, 2014, overthrow of his ally Viktor Yanukovych. The pro-West faction of Ukraine's Parliament took over the government.6 The crisis occurred because Yanukovych mismanaged the budget and forced Ukraine to ask for financial help. It appealed to the EU, then Russia, causing political unrest. Those who wanted to be closer to the EU objected when that solution was abandoned. Russia's military strike supported Yanukovych's return to Kiev and closer ties to Russia.

We can urge that the school:
(a) is a micro unit
(b) is where secondary socialization takes place.
(c) has a formal curriculum.
( d) plays the same role as family
Clarification:
I found the complete exercise online:
"Choose the correct combination below:
1. a
2. d
3. c and d
4. b and c"
Answer:
4. b and c
Explanation:
Option B is correct because schools are the place where individuals learn to behave while in groups, it doesn't take place at home because this type of socialization has to be wider than the individual’s family circle. Option C is also correct because schools have a formal curriculum that tells what students need to know and what they need to accomplish to graduate; there are requirements for the students to complete their studies, specific knowledge they need to know.

Martell is writing an essay with the following claim
Answer:
The statement he should include to best anticipate and respond to a counterclaim is:
C. While the school board may be concerned that an after-school computer lab would be too costly, the school could save money by asking local college students to work as volunteer tutors.
Explanation:
Martell's claim is that the school should open an after-school lab so that students can use the computers to finish homework and projects that are computer based. A counterclaim to that will be a statement that presents a reason why creating the lab may be a bad idea. The counterclaim has to make sense, as well as Martell's response to it (the solution he offers to the counterclaim).
In letter A, the counterclaim is weak. It does not present a reason against the lab; it simply states there are people who disagree with it. We can eliminate this option.
Letter B does present a reason, but the problem is the response. It is subjective, personal. Martell would be basically attacking anyone who disagrees with him. Thus, we can also eliminate this option.
Letter C is the best option. It does present a reason - the lab could cost a lot of money - and a solution - finding volunteers to work in in. This is the choice Martell should make.
Letter D presents a response that has nothing to do with the counterclaim itself. It is also incorrect.

Explanation:
Desmond told his two friends, Marley and Brianna, that he was awarded a $10,000 grant for college if he becomes a math or science teacher. Desmond wants to teach physics.
Marley told him he should take the grant. Brianna told him not to take the grant. Which statement about their advice is true?
Marley is correct because a grant is like a gift and he can still get scholarships or loans to pay for the rest of his expenses.
Marley is correct because he can take the grant and then study whatever he chooses without paying it back if he changes his mind about his career.
Brianna is correct because he cannot get scholarships if he takes the grant and scholarships would pay more of his education costs.
Brianna is correct because grants are like loans and must be paid back. He should wait and see what scholarships and work-study programs he qualifies for.
Answer:
Marley is correct because a grant is like a gift and he can still get scholarships or loans to pay for the rest of his expenses.

PLEASE MARK BRAINLIEST!!!!!!!!!!Ask yourself this question: How am I of value to myself to others and to what I believe in?
Answer:
I am of value to myself, others, and what I believe in because it is in my belief that everyone matters. Everyone has value, a purpose. Some just don´t know what it is yet.
Explanation:
This probably didn´t help so sorry if it didn´t, I don´t really think there is a right answer. Anyways I hope this helped, have a great day!
Value remains a very debatable word, where a person can attach his own values to his own thinking and not what the society wants him to believe in. So, one should always value oneself first, get to know oneself first and then cater to the values people hold for them.
One should also consider that everyone has their own struggle to cater to, and thereby, one should always believe in respecting people's boundaries and try to empathize with people.
What is Value?Value is the idea of oneself, how one should portray oneself in society, as well as in front of himself, and should cater to the ideas one has grown up with, and take decisions accordingly, which adds up to a person's personality as well.
What are Boundaries?People's boundaries are the lines that people draw between their public space and private space, that other people should respect and not invade.

I need help what’s the answer for these 3 questions
Answer:
Over ocean-- warmer temperature and low air pressure.
Over the land--- cool temperature and higher air pressure.
Explanation:
The air pressure is low in the ocean and higher over the land whereas the temperature over the ocean is warmer and cooler over the land because the land loses heat very quickly when the sun goes down while on the other hand, water of the ocean can't lose the heat very quickly which remain them warmer. This variation in temperature causes the low surface pressure to shift to the ocean and the high surface pressure to move over the land at night.

How could a car wash be a financially viable
informal business option for unemployed people
In your community?
Answer: A car wash can be of viable importance to the unemployed in the society in a number of ways. Ways in which a car eash could be a financially viable business option.
A car wash does not require expertise: in our own society , to open a carwash does not require a person to go to school to get the know-how .One just needs to know how to use soap and water to clean a car.this makes it easy for anyone to start and keep financially stable.
A car wash requires little startup capital; it will only cost an entrepreneur just soap and a water-point to start up the car wash in a our society. Therefore a very viable means of finance to him. In our community, car wash is a viable business option for unemployed because still automatic washing is not deployed and service stations rely highly on people who can wash the cars/vehicles. Also it does not require a specific qualification nor it is a very skilled task, hence it is easier to work the given tasks. Additionally, the more cars a station can cover, the more will be its utility or basic operating cost. brainly?

Dr. Miller conducts a study examining the relationship between the number of friends one has and the experience of daily stress and life satisfaction. Dr. Miller decides to create a scatterplot of the relationship between daily stress and life satisfaction, but in doing so, she realizes there are three scores that seem to be very extreme and are nowhere near the other points on the scatterplot. Specifically, it appears that three people report very high levels of daily stress and very low levels of life satisfaction. Dr. Miller should probably consider these scores _________.
Answer:
Dr. Miller should probably consider these scores _________.
Outliers
Explanation:
An outlier is an abnormal observation that lies two standard deviations away from other values in a random population sample. For example, the three people who report very high levels of daily stress and very low levels of life satisfaction are outliers. They have extreme scores that are not within the average or mean scores recorded in Dr. Miller's scatterplot.
