1. Write the formula for the one-sample t statistic. 2. Why is the t statistic sometimes called Student's t? 3. You are given seven scores: 73, 42, 51, 68, 49, 62, and 57. How many of does this set of scores possess for calculating (a) X, (b) s, and (c) s?? 4. You plan to compute the one-sample t statistic on samples of the following sizes For each sample, find the df. (a) N = 10, (b) N = 16, (c) N = 7, (d) N = 54 (e) N = 120, (f) N = 30. 5. You have two theoretical sampling distributions of t, one with 13 of and one with 27 df. Which distribution will be wider and flatter? 6. Under what conditions will the sampling distribution of the t statistic be identical to the sampling distribution of z
