model: firm return - risk free return = beta(market return - risk free return)
hypothesis1: group1 & group2 have equal betas
hypothesis2: group1 & group2 have equal variances
if there are 500 observations (250 in group 1, 250 in group 2), what are the critical values for 1%, 5%, and 10% significance levels for t-test, chow test (hypothesis1), and f-test(hypothesis2)? how to use the tables for these tests? thank you for your help.
