# Question: Here is the regression for Exercise 3 with an indicator

Here is the regression for Exercise 3 with an indicator variable:

Dependent variable is: US Gross($M)

R-squared = 0.193, Adjusted R-squared: 0.166

s = 37.01 with 62 - 3 = 59 degrees of freedom

a) Write out the regression model.

b) In this regression, the variable R Rating is an indicator variable that is 1 for movies that have an R rating. How would you interpret the coefficient of R Rating?

c) What null hypothesis can we test with the t-ratio for R Rating?

d) Can you reject the null hypothesis of part c? Explain.
