Question

The National Sleep Foundation reported a moderately strong positive association between the number of hours of sleep a person gets and the person’s ability to listen, learn, and solve problems.

a. Explain in the context of this problem what “positive association” means

b. Hoping to improve academic performance, the professor recommends allowing students to take a nap prior to taking midterms and finals. Discuss the professor’s recommendations.

Answer 1

(A) Positive association means that there is a positive relationship between the number of hours of sleep a person gets and the person's ability to listen,learn and solve problems.

This means that the more number of hours of sleep a person gets, more will be the person's ability to listen,learn and solve problems.

(B) Based on the given results of a moderately strong positive association, I think that the professor has given good recommendations as we can see that there is a positive association between the number of hours of sleep a person gets and the person's ability to listen,learn and solve problems. So, it is recommended to a nap prior to taking midterms and finals for better result.
