To test Ho: o=2.8 versus H₁: <2.8, a random sample of size n = 21 is obtained from a population that is known to be normally distributed. H (a) If the sample standard deviation is determined to be s=1.3, compute the test statistic. x= 4.311 (Round to three decimal places as needed.) (b) If the researcher decides to test this hypothesis at the a=0.10 level of significance, determine the critical value. The critical value is (Round to three decimal places as needed.)
