lest. Optional Final Exam This question: 1 point(s) possible To test Ho: H = 100 versus H,: # 100, a simple random sample size of n = 21 is obtained from a population that is known to be normally distributed. Answer parts (a)-(d). Click here to view the t-Distribution Area in Right Tail. (a) If x = 104 and s = 8.3, compute the test statistic. t=(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 values. The critical values are (Use a comma to separate answers as needed. Round to three decimal places as needed.) (c) Draw a t-distribution that depicts the critical region(s). Which of the following graphs shows the critical region(s) in the t-distribution? OA O B. O c. Q (d) Will the researcher reject the null hypothesis? O A. The researcher will reject the null hypothesis since the test statistic is between the critical values. O B. There is not sufficient evidence for the researcher to reject the null hypothesis since the test statistic is between the critical values. O C. The researcher will reject the null hypothesis since the test statistic is not between the critical values. O D. There is not sufficient evidence for the researcher to reject the null hypothesis since the test statistic is not between the critical values
