The statsmodels ols() method is used on an exam scores dataset to fit a multiple regression model using Exam4 as the response variable. Exam1, Exam2, and Exam3 are used as predictor variables. The general form of this model is:
Y-hat equals beta sub zero plus beta sub one times Exam1 plus beta sub two times Exam2 plus beta sub three times Exam3. Exam1, Exam2, and Exam3 are variables.
If the level of significance, alpha, is 0.10, based on the output shown, is Exam1 statistically significant in the multiple regression model shown above? Select one.
