To test Ho: o = 2.1 versus H: 0+2.1, 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 = 1.8, compute the test statistic.
= 11.755 (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 values.
