Estimate the population regression model. TestScore-B+B STR+English+(STR x English) + where English is the percentage of English Learners in school district i. Using the estimation results we wish to test the hypothesis below. H: 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 a. Since the OLS estimate is not significant at the 5% level, we should reject H Ob. The sample correlation coefficient between English and the interaction term (STRX English) is greater than 0.98. Thus, we should drop English or (STRX English) to avoid perfect multicollinearity. Oc.

QUESTION 7
Estimate the population regression model.
TestScore-B+B STR+English+(STR x English) +
where English is the percentage of English Learners in school district i. Using the estimation results we wish to test the hypothesis below.
H: 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
a. Since the OLS estimate is not significant at the 5% level, we should reject H
Ob. The sample
Oc. The p-value for testing His between 0.01 and 0.05.
d. We cannot reject H at the 5% significance level.
e. We cannot test Hbecause we do not include in the model the dummy variable for school districts with a high proportion of English learners 0
