a) Check the assumption of homogeneity of variance using F-max. b) Do the data indicate a significant difference between the two groups? Test at the .01 level of significance.Write the detailed steps for hypothesis testing. c) What is Cohen Solution a) F=S1^2/S2^2=740^2/660^2=1.25 F for 99% Confidence and 7,7 df is:6.99 since calculate dvalue is less than table value we fail to reject null hypothesis.
