question 17 part b, please 

thanks

To test Ho: o = 2.2 versus H,: o<2.2, a random sample of size n= 19 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. = 23.244 (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 value. The critical value is (Round to three decimal places as needed.)
