Maybe 9. In question #7 , why is the t-distribution used rather than the z-table? A. B. C. D. Because the population standard deviation is known. Because the population standard deviation is unknown. Because the t-distribution is more accurate. Because the z-table is less accurate. 10. If you had known the population standard deviation rather than the sample standard deviation "s" what would the p-statistic have been? A.-0.0202 B. -2.051 C. -0.4798 D. -0.0404 11.
