To test Ho: 6 = 2.2 versus H, : 0> 2.2, a random sample of size n = 24 is obtained from a population that is known to be normally distributed. (a) If the sample standard deviation is determined to be s = 2.5, compute the test statistic. (b) If the researcher decides to test this hypothesis at the a = 0.10 level of significance, use technology to determine the P-value. (c) Will the researcher reject the null hypothesis? (a) The test statistic is (Round to two decimal places as needed.)
