We are testing the hypothesis that μ≤μ0. If the p-value comes out as 0.034 for a given sample size, then, all other things being equal, what would the p-value be if the sample size is cut in half? (Assume that both the original sample size and the halved sample size are large samples.)

For a one-tailed hypothesis test (upper tail) the p-value is computed to be 0.034. If the test is being conducted at 95% confidence, the null hypothesis Select one: a. is rejected. b. is not rejected. c. could be rejected or not rejected depending on the value of the mean of the sample. d. could be rejected or not rejected depending on the sample size.

Suppose that we are testing the null hypothesis that μ = 68 versus the alternative that μ < 68. We take a sample of size 36 and find a sample average of = 63.4 and a sample standard deviation of s = 12.6. Determine the value of the test statistic for the hypothesis test of one population mean. t = -2.19 t = -0.37 t = 0.37 t = 2.19

If we are testing the hypothesis H0: p = 0.5 vs. H1: p > 0.5 where p represents the proportion of American adults who would not be concerned if NSA collected records of personal telephone calls. When would you conclude that the data provide enough evidence that the proportion of adults who would not be concerned is 0.5? A. Never B. When exactly half of the people in the sample say they would not be bothered. C. When the p-value...
