Question

(e) Perform a two-sample (nonpooled) t-test to determine if there is a difference in the average height of men and the average height of women.

Note 1: for the assumptions, there is a bit of knowledge about the variable height that will get you out of making the normal probability plots. You are welcome to state that piece of knowledge OR make the NPPs.

Note 2: I highly recommend you make this faster and easier for yourself by using Data > Data Analysis > t-Test: Two-Sample Assuming Unequal Variances.

(f) What clues tell you this should be a two-sample (nonpooled) t-test as opposed to paired t-test?
