To test Ho: o = 2.6 versus H,: o<2.6, a random sample of sizen=21 is obtained from a population that is known to be normally distributed. (a) If the sample standard deviation is determined to be s = 1.3, compute the test statistic. = 5 (Round to three decimal places as needed.) (b) If the researcher decides to test this hypothesis at the a = 0.05 level of significance, determine the critical value. The critical value is (Round to three decimal places as needed.)

To test Ho: o = 2.6 versus H, :o<2.6, a random sample of size n= 21 is obtained from a population that is known to be normally distributed. (a) If the sample standard deviation is determined to bes= 1.3, compute the test statistic. = 5 (Round to three decimal places as needed.) (b) If the researcher decides to test this hypothesis at the a = 0.05 level of significance, determine the critical value. The critical value is (Round to three decimal places as needed.)
