In the summer-job example, x1 = 725, n1 = 802, x2 = 573, n2 = 712. Compute p̄. Round to 3 decimals.

A researcher claims that the proportion of male students with summer jobs is greater than the proportion of female students with summer jobs. Which pair is correct?

In matched-pairs tests, the focus of the hypotheses is on the mean difference μd.

Sample A has s = 2.4. Sample B has s = 4.8. Compute the F test statistic after proper labeling. Round to 3 decimals.

A newspaper claims there is no difference between Dee’s and Tom’s mean ratings. Dee’s sample has x̄1 = 4.7, s1 = 0.50, n1 = 100. Tom’s sample has x̄2 = 4.8, s2 = 0.62, n2 = 100. Use α = 0.01 with two-tail critical values ±2.576. Is the claim supported? Answer “supported” or “not supported”.

In the summer-job study, p̂male = 725/802 and p̂female = 573/712. What is the approximate TS for males as Sample 1?

A two-sample mean test has n1 = 30 and n2 = 31. What df should be used?

Sample A has s = 5.5. Sample B has s = 3.0. Compute the F test statistic after proper labeling. Round to 3 decimals.
