You are interested in the relationship between video games and physical activity, so you collect information from a random sample of individuals on how many hours per week they play video games (V) and how many hours per day they exercise (E). Using this data, you calculate the following sample averages:
V 2.1
V2 7.8
E 7.2
E2 60.1
VE 13.8
Calculate the OLS estimate of the slope for the following regression model:
V = beta0 + beta1 E + u
