The following results are from data where the dependent variable is EXPENSE FEES, the independent variables are SAFETY RATING, PERFORMANCE, and LOAD which is a dummy variable = 1 for load funds and = 0 for no-load funds. d) What is the standard error of the error term in the regression equation? e) Are any of the explanatory (independent) variables significant at the 10% level of significance? How do you know? f) What is the null and alternative hypothesis that Excel is testing in reporting the t-stats above?
