to test the H0 2.2

To test Ho: 6 = 2.2 versus H, : o # 2.2, a random sample of size n = 17 is obtained from a population that is known to be normally distributed (a) If the sample standard deviation is determined to be s = 1.6, compute the test statistic. x2 - 8.463 (Round to three decimal places as needed.) (b) If the researcher decides to test this hypothesis at the u = 0.05 level of significance, determine the critical values. The critical values are X6 025 = and X0 975= (Round to three decimal places as needed.)
