A test to verify that there is no difference between two populations means of dependent samples, based on a sample of 53 observations, resulted in a test statistic of 1.759 and a variance of the difference between sample means of 7.985. The difference between the two sample means is... Select one: A. 4.53 В. 1.93 C. 0.26 D. 0.68

Question
A test to verify that there is no difference between two populations means of dependent samples, based on a sample of 53 observations, resulted in a test statistic of 1,759 and a variance of the difference between sample means of 7.985. The difference between the two sample means is... Select one: A. 4.53 В. 1.93 С. 0.26 D. 0.68 p-values can only be determined for hypothesis tests about one mean, not differences in means. Select one: A. More information is needed. B. False. C. True. You perform a test on the difference between two population means and obtain statistic of 2.5. you know ox = 7.1, ơy = 5.44, nx = 20, ny = 20 and y = 9, then x is... Select one: A. 14.0 B. 10.97 C. 13.0 D. 10.56 There can only be an upper-tail or two-tail test when testing for the variance of a normal population. Select one: A. More information is needed. B. False O C. True.
