Suppose we would like to find a relationship between the number of credits a student is enrolled in (X) and how many hours they work a week (Y). Suppose the average number of credits a student is enrolled in is 13.2 with a standard deviation of 2.5 and the average number of hours a student works a week is 7.8 with a standard deviation of 4.2. The correlation between these two variables is -0.42. Predict the number of hours a student works if they are enrolled in 15 credits. 9.1 6.5 7.4 24.3

Explanation / Answer

1) predicted value = 7.8 - 0.42*4.2/2.5 (15 - 13.2) = 6.5

2) p value = 0.083, So answer is between 0.05 and 0.1

3) p value = 0.336, So answer is Greater than 0.2
