The true mean hours of sleep a night of college students in the United States is 6.2 hours. Suppose you want to use a hypothesis test to determine whether the mean hours of sleep a night of BYU-Idaho students is higher than the national mean. Which of the following pairs of hypotheses is the most appropriate for addressing this question?H_o : mu = 6.2 qquad H_a : mu > 6.2 H_o : mu > 6.2 qquad H_a : mu = 6.2 H_o : mu = 6.2 qquad H_a : mu != 6.2 H_o : mu != 6.2 qquad H_a : mu = 6.2 H_o : mu = 6.2 qquad H_a : mu < 6.2 H_o : mu < 6.2 qquad H_a : mu = 6.2

Option A)

Step-by-step explanation:

We are given he following in the question:

Population mean = 6.2 hours.

The hypothesis wants to determine if the mean hours of sleep a night of  students is higher than the national mean.

Thus, we can design the null and alternate hypothesis as:

The null hypothesis states that mean hours of sleep a night of students is equal to the national mean that is 6.2 hours.

The alternate hypothesis states that mean hours of sleep a night of students is higher than the national mean that is 6.2 hours.

Thus, the correct answer is

Option A)

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
