1. Using the MM207 Student Data Set:

a) What is the correlation between student cumulative GPA and the number of hours spent on school work each week? Be sure to include the computations or StatCrunch output to support your answer

Correlation between Q10 What is your cumulative Grade Point Average at Kaplan University? and Q11 How many hours do you spend on school work each week? is:

0.27817234

b) Is the correlation what you expected? No because I assumed the more hours you study the higher your GPA should be.

c) Does the number of hours spent on school work have a causal relationship with the GPA? Yes

d) What would be the predicted GPA for a student who spends 16 hours per week on school work? Be sure to include the computations or StatCrunch output to support your prediction. 3.6
