![The ols() method in statsmodels was used to fit a simple linear regression model
using "Exam4" as the response variable and "Exam1" as the predictor variable. The
output is shown below. A text version is available. What is the correct regression
equation based on this output? Is this model statistically significant at 5% level of
significance (alpha= 0.05)? Select one.
