If the researcher decides to test this hypothesis at the = 0.01 level of significance, determine the critical value. The critical value is_. Round to three decimal places as needed.

Extracted text: To test Hn o= 2.4 versus H, 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 = 2.7, compute the test statistic. x- 18 984 (Round to three decimal places as needed.) 0. (b) If the researcher decides to test this hypothesis at the a= 0.01 level of significance, determine the critical value. x6 01 (Round to three decimal places as needed.) X0.01
