Researchers claim that 60 tissues is the average number of tissues a person uses during the course of a cold. The company who makes Kleenex brand tissues thinks that the claim is untrue, but is not sure whether the average is greater than or less than 60. What are their null and alternative hypotheses?

Answers

Answer 1

Answer:

H0 : μ = 60 and H1 : μ ≠ 60

Explanation:

H0 : μ = 60 and H1 : μ ≠ 60

Where ;

H0 = the null hypothesis

μ = mean value

H1 = alternative hypothesis

The null hypothesis is our initial assumption, which is the claim that the average number of tissue used during the course of a cold is 60.

The alternative hypothesis will look to negate the null hypothesis, which is to establish that the mean number of tissues used during the course of a cold is not 60, meaning it could be less or more.

Ria is an Indian student who was admitted to a US university. Her annual tuition is $42,000. She has to pay her tuition fees in US dollars. She needs to calculate how many Indian rupees she will need to buy one dollar. The dollar to rupee exchange rate is 63.76 and rupee to dollar exchange rate is 0.015. How many Indian rupees will Ria need to buy one dollar?
A.
50.00 rupees
B.
56.00 rupees
C.
63.76 rupees
D.
76.63 rupees

Answers

The correct answer is C. 63.76 rupees

Explanation:

In the economy, the exchange rate is the one that defines the equivalence between two currencies of different countries or economical zones. This means by using the exchange rate you can determine how many rupees you need to buy one dollar and vice versa. According to this, if the dollar to rupee exchange is 63.76 this means 1 dollar = 63.76 rupees, and therefore you will need 63.76 rupees to get one dollar. On the other hand, if you have 1 rupee this is equivalent to 0.015 dollars as this is the exchange rate rupee to dollars. Thus, to buy one dollar Ria will need to have 63.76 rupees because this is the exchange rate for the two currencies.

Answers

Answer: "Charles feared that the big and scary dog would jump over the short, metal fence."

A comma should be placed between the adjectives that describe the noun fence. The reason is that they are not joined by a coordinating conjunction as in the description about the dog: big and scary dog. As a result, since they appear in the form of list without any linking words, they must be separated by a comma.

become important cultural centers during the

Renaissance?

Answers

The correct answer to this open question is the following.

Although there is no text attached or any further reference to it, we can say that Italy's states became important cultural centers during the Renaissance because rich and prominent Italian families such as the Medici, sponsored many artists during the Renaissance. The Medici were the most powerful family in the city-state of Florence. They sponsored the work of artists such as Leonardo Da Vinci.

During the Renaissance, other important artists flourished, as was the case of the magnificent Michel Angelo Buonarroti, creator of the ceiling paintings of the Sixtine Chapel or the figure known as "La Pieta."

In 30 words or fewer, when you think of the word "industrial," what comes to mind?

Answers

Answer:

New York

Explanation:The city in the 50's and the 60's it was busy and lots of people had minimum wage jobs.

There are many things that come to mind when I think of the word "industrial." First, I picture factories and massive production lines.

Heavy machinery, assembly lines, and employees wearing protective gear are typical features of industrial locations. Automation and technological breakthroughs have also been brought about by industrialization. The introduction of mass production and urbanization during the Industrial Revolution in the 18th and 19th centuries drastically altered society.

Significant improvements were made in manufacturing, transportation, and agriculture as a result. Increased pollution and job possibilities are two examples of how industrial growth affects the environment and society. In conclusion, the word "industrial" conjures up pictures of production lines, manufacturing equipment, modern technology, and the historical effects of industrialization.
