According to the National Sleep Foundation, an adult between the ages of 18 and 25 should be getting between 7 and 9 hours of sleep per night. Since college students are so busy with studying and other responsibilities, it seems likely they are not getting the recommended hours of sleep.  I would like to see what is true for the GVSU student body.

Is there sufficient evidence to suggest that GVSU students get less than the recommended 7 hours of sleep on average per night?

Select the correct parameter definition.

A) µ = MEAN hours of sleep per night for GVSU students

B) µ = MEAN hours of sleep per night for GVSU students is less than 7 hours

C) µ = MEAN hours of sleep per night for 2264 GVSU students

D) = MEAN for GVSU students who sleep 7 hours a night

Expert Solution

Here we are given that,

According to the National Sleep Foundation, an adult between the ages of 18 and 25 should be getting between 7 and 9 hours of sleep per night. Since college students are so busy with studying and other responsibilities, it seems likely they are not getting the recommended hours of sleep.

Also, it is given that,

We would like to see what is true for the GVSU student body.

Is there sufficient evidence to suggest that GVSU students get less than the recommended 7 hours of sleep on average per night?

Now, from the given alternatives,we have to select the correct parameter definition.

A) µ = MEAN hours of sleep per night for GVSU students

B) µ = MEAN hours of sleep per night for GVSU students is less than 7 hours

C) µ = MEAN hours of sleep per night for 2264 GVSU students

D) = MEAN for GVSU students who sleep 7 hours a night

ANSWER:- A) µ = MEAN hours of sleep per night for GVSU students

Explanation:- Here, we have to select the correct Parameter definition.

The parameter is a function of Population.

Here, our Population is all GVSU students. So, we should consider all the students of GVSU irrespective of their sleeping hours. So, Option A is the correct alternative.

This answers your question.

If you have understood the answer please rate Positively.

The National Sleep Foundation (NSF) recommends that college students get between 8 and 9 hours of sleep per night. Not believing this is happening at a local college, a random sample of 20 students resulted in a mean of 6.94 hours, with a standard deviation of 1.1 hours. Part 1 of 3 If it is assumed that hours of sleep for college students is approximately normally distributed, construct and interpret a 95% confidence interval statement as well as a confidence...

The National Sleep Foundation used a survey to determine whether hours of sleep per night are independent of age (Newsweek, January 19, 2004). A sample of individuals was asked to indicate the number of hours of sleep per night with categorical options: fewer than 6 hours, 6 to 6.9 hours, 7 to 7.9 hours, and 8 hours or more. Later in the survey, the individuals were asked to indicate their age with categorical options: age 39 or younger and age...
