To test Ho: H= 40 versus H,: u< 40, a random sample of size n=25 is obtained from a population that is known to be normally distributed. Complete parts (a) through (d) below. E Click here to view the t-Distribution Area in Right Tail. (a) If x = 37.4 and s= 13.6, compute the test statistic. to = - 0.956 (Round to three decimal places as needed.) (b) If the researcher decides to test this hypothesis at the a = 0.05 level given. significance, determine the critical value(s). Although technology or a t-distribution table can be used to find the critical value, in this problem use the t-distributic Critical Value: - 1.711 (Round to three decimal places. Use a comma to separate answers as needed.) (c) Draw a t-distribution that depicts the critical region. Choose the correct answer below. O A. OB. Oc. Q -/2 0 /2
