Question:
- Calculate the Pearson correlation between months enrolled and the number of minutes spent on homework for members of this class. Graph the relationship, determine a hypothesis to test this relationship, and statistically test this hypothesis using alpha=0.05. Interpret all results in a paragraph citing the appropriate statistics.

2. Using the same data above: Calculate the simple linear regression to determine if the time spent on homework (y) can be predicted by the months enrolled (x). Graph the relationship and determine, numerically, if there are any outliers. Interpret all results in a paragraph citing the appropriate statistics.
