Remember to SHOW ALL YOUR WORK, and INCLUDE ALL STEPS for hypothesis tests.

1. A sociologist is investigating the relationship between life satisfaction and sociability. For a sample of 16 individuals, the following data is obtained:

SP = 5.14
Sociability: M=10.62 SS=5.12 Life Satisfaction: M=9.53 SS=7.24

a. Compute the correlation between sociability and life satisfaction.
b. What can be said about the nature of the relationship between these two variables? c. Compute the coefficient of determination. What does this value tell you?
d. Conduct a hypothesis test to determine if the correlation is significant.

For all hypothesis tests, be sure to include information for all 7 steps. For any two-sample or paired t-tests that you perform, in Step 6, show the decision rule based on BOTH the critical value and the p-value. Use the online app for the t-distribution to compute your p-values.
