+ Estimate the population regression model, TestScore; = Bo+B1 STR; + B2English; + B3(STR;x English;) + u; where English, is the percentage of English Learners in school district ;. Using the estimation results we wish to test the hypothesis below. Ho : The effect on test score of class size does NOT depend on the percentage of English learners. Choose the correct
statement on the estimation results and/or hypothesis testing. Since the OLS estimate B2 is not significant at the 5% level, we should reject Ho b. The sample correlation coefficient between English and the interaction term (STR x English) is greater than 0.98. Thus, we should drop English or (STR x English) to avoid perfect a. multicollinearity. C. The p-value for testing Ho is between 0.01 and 0.05. d. The heteroskedasticity F-statistic for testing Ho is greater than the critical value for the 10% significance level. e. We cannot test Ho because we do not include in the model the dummy variable for school districtis with a high proportion of English learners.
