Below is a regression predicting the weekly hours of study (dependent variable) using the weekly amount of exercise (independent variable) for SOC 396 stats students. Please write out the equation and report the r² and the p-value for the effect. Then explain the effect in words that non-statistically-inclined 12-year-olds might understand. How much variance in studying is explained by exercise?

Is the effect statistically significant? Is it substantively significant (yes, do some math)? Does this make you want to increase your workouts or not?
