Use the following to answer the questions below:

Data were collected on GPA and number of Facebook friends for students in a small statistics class. Some summary statistics, partial output from the regression analysis, and a scatterplot of the data (with regression line) are provided. Assume that students in this class are typical of all students at the university.

Use three decimal places when reporting the results from any calculations, unless otherwise specified.

 Variable Mean StDev Minimum Maximum GPA 3.2067 0.4118 2.4000 3.9500 FacebookFriends 677.9 307.2 185.0 1500.0

The regression equation is GPA = 3.830 - 0.000919 FacebookFriends

 Source DF SS MS F P Regression 1 2.31193 2.31193 24.85 0.000 Error 28 2.60534 0.09305 ​ ​ Total 29 4.91727 ​ ​ ​

The correlation between GPA and number of Facebook friends is -0.686. Use the correlation and α = 0.05 to test for a negative linear association between GPA and number of Facebook friends. Include all details of the test.
