a) Run the appropiate test to evaluate the equality of variances for several populations. Report the p-value of this test

b) Do you reject or fail to reject the null hypothesis of equal variances.?

c) Run the appropiate test to evaluate the normality of the residuals for the test for several populations. Report the p-value of this test ___________ and your conclusion reject/fail to reject _______________ the null hypothesis (of normality.)

d) Report the hypothesis you are testing about equality of means and your overall conclusion. Use =0.05
