A health psychologist knew that corporate executives in general have an average score of 2.55 with a standard deviation of 0.5 on a stress inventory and that the scores are normally distributed. In order to learn whether corporate executives who exercise regularly have different stress scores, the psychologist measured the stress of 30 exercising executives and found them to have a mean score of 2.76. a. Using the five steps of hypothesis testing, was the group of 30 exercising executives different from executives in general? (Use the .05 significance level.) Be sure to sketch the distributions involved. Be sure to fully state the five steps and show ALL calculations/work. b. Additionally, explain the logic of what you did to a person who understands hypothesis testing for studies in which the sample consists of a single individual but is unfamiliar with hypothesis testing involving a sample of more than one individual. (Be sure your explanation includes a discussion of the distribution of means--what it is, what it is made of, the concept of how it is created, how itʹs characteristics are created, its role in the overall hypothesis testing process.)
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Population mean (μ) = 2.55
Population standard deviation (σ) = 0.5
Sample size (n) = 30
Sample mean (x) = 2.76
α = 0.05
STEP 1:
Stress score in general executive (s1)
Stress score in exercising executive (s2)
Null : s1 = s2
Alternative : s1 < s2
STEP 2:
Shape of distribution = normal
Population mean (μ) = 2.55
Population standard deviation (σ) = 0.5
Sample size (n) = 30
Sample mean (x) = 2.76
α = 0.05
Decision rule :
α = 0.05 which corresponds to a t score (t0) ;
df = n - 1 = 30 - 1= 30 at 0.05 = 1.699
If :
(Test statistic (t) > t0) ; reject the Null
(right tailed test)
Test statistic (t) :
(x - μ) / (σ/√n)
(2.76 - 2.55) / (0.5/√30)
0.21 / 0.0913
= 2.30
t > t0
2.30 > 1.699
t is more extreme than t0
Hence, reject the null at α = 0.05

At a certain location, the number of hours of sunlight is modeled by y = 6.4 cosine (StartFraction pi Over 26 EndFraction x) + 12 where x represents the number of weeks after the summer solstice.

3.2
5.6
6.4
13.0
Answer:
5.6
Step-by-step explanation:
Edge 2020
A correct option is an option (b)
Given,
The function is [tex]y=6.4 cos(\frac{\pi x}{26})+12[/tex]
For minimum hours of sunlight, [tex]cos(\frac{\pi x}{26})[/tex] should have the lowest value, that is -1 for [tex]x=26[/tex] {because [tex]cos (\pi )=-1[/tex] is the lowest value of cosine function}
Thus.
[tex]y_{minimum} = -6.4 + 12 \\y_{minimum}= 5.6[/tex]
So, the option is an option (b)

Can someone help me with 14 and a few others I need help ):
Answer:
26, -0.85, 17
Step-by-step explanation:
hi! so for 14, you can plug in -11 for every x in the equation.
f(-11)= 15-(-11)
=15+11
=26
your answer is 26.
for 15, we can plug in 0.3 for x.
g(0.3)=-2.5(0.3)-0.1
= -0.75-0.1
= -0.85
your answer is -0.85.
for 16, you can plug in -17 for x.
f(-17)= -(-17)
=17
your answer is 17.
Answer:
14: 26
15: -8.5
16: 17
Step-by-step explanation:
The f(x) basically gives you what x is, as the inside of parenthesis means the value of x. You then can plug in x into the equation for each of the equations. Whenever you get something like 24- (-42) The negatives cancel out and you add the two values together instead.

Answer:
It is B
Step-by-step explanation:
If you find the perimeters of each of the rectangles, you get 11x2, 15x2, and then 19x2
How did I get the x2?
All you have to do is add the length and width together, but it only gives half of the perimeter as there is another half at the other corner of the rectangle. The 11, 15, and 19 was from adding the 4s with the 7s. In the first rectangle, you do 7+4 equals 11, but you have to multiply it by 2, hence the first sentence at the beginning. Then you can find the slope, or the rate of change, as it increases by intervals of 8. The four that is added to every extra rectangle added to it is multiplied by 2, because there is another four at the other side of the rectangle. Then you can find the answer using process of elimination because B, is the only answer that the y-values increase by 8, while the x-values increase by 1, as the x values are counting how many rectangles are in each rectangle.
Hope this helps!

what is 8.42 times 10 to the 3rd power
Answer:
8420
Step-by-step explanation:
10 to the third power will move the decimal point three place values to the right. So, the first two times you move it, you get 842, and so there is a 0 on the end to signify that it moved the third time.
karinne hit 4 more home runs than 1/2 the number of home runs Lu hit. Together they hit 10 home runs. Let X represent the number of home runs Lu hit. Write an equation to represent the situation
It is given that Lu hit x numbers of home run.
So, number of home run hit by Karinne is more home runs than 1/2 the number of home runs Lu hit.
So, number of home run Karinne hit is :
[tex]y = 4 + 0.5x[/tex]
Also,
[tex]x + y = 10[/tex]
Solving above two equation, we get :
x + ( 4 + 0.5x ) = 10
1.5x + 4 = 10
1.5x = 6
x = 4
Therefore, number of home run hit by Lu is 4.
Hence, this is the required solution.
Creating a mathematical expression using the scenario described, the expression which represents the total number of home runs is 1.5x + 4 = 10
Total Number of home runs :
(1/2)x + 4 + x = 10
1.5x + 4 = 10
1.5x = 10 - 4
1.5x = 6
x = 6/1.5
x = 4
Therefore, the equation which represents the situation is 1.5x + 4 = 10
