To test Ho: o=2.4 versus H₁: o>2.4, a random sample of size n = 16 is obtained from a population that is known to be normally distributed. Complete parts (a) through (d). *** (a) If the sample standard deviation is determined to be s=2.2, compute the test statistic. x= 12.604 (Round to three decimal places as needed.) (b) If the researcher decides to test this hypothesis at the a= 0.01 level of significance, determine the critical value. X301=(Round to three decimal places as needed.)
