4. What is the formula of the linear regression, and correlation of these two data sets?
yhat = 132.1x - 0.194
5. Create a boxplot of students who do/do not have a twitter vs. time spent on social media.
6. Compare the means of both sets, which one is higher?
The mean is higher for people who have a twitter because they are on social media more often.
