Here are some data on cholesterol levels for young men and young women. Men Women 110 | 120 120 130 130 140 130 150 140 160 150 170 160 190 170 200 180 200 200 220 220 230 a. Determine if the variances in cholesterol levels based on these samples are equal. Hint: state the null and alternative hypotheses, perform an F-test two-sample for variances, describe your findings. b. Indicate if the two means are equal. Hint: state the null and alternative hypotheses, perform a t-test based on the results of part a, describe your findings.
