a) Find the mean hours of exercise per week by the participants.
b) Find the variance and standard deviation of the hours of exercise per week by the participants.
c) Run a bivariate correlation to determine if there is a linear relationship between the hours of exercise per week and the life satisfaction. Report the results of the test statistic using correct APA formatting.
d) Run a linear regression on the data. Report the results, using correct APA formatting. Identify the amount of variation in the life satisfaction ranking that is due to the relationship between the hours of exercise per week and the life satisfaction (Hint: the R2 value)
e) Report a model of the linear relationship between the two variables using the regression line formula.
