Question

To test Ho 100 versus H1 : 100, a simple random sample size of n = 22 is obtained from a population that is known to be normally distributed. Answer parts Click here to view the t-Distribution Area in Right Tail (a) If x = 104.4 and s-99, compute the test statistic. t(Round to three decimal places as needed.) (b) If the researcher decides to test this hypothesis at the = 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. OB. O C.

Explanation / Answer

A) test statistic = (X bar - mean) /(s/sqrt(n))

= (104.4 - 100)/ (9.9 / sqrt(22))

= 2.085

B) critical values = + t0.005,21 =+ 2.831

C) Option-C)

D) Option-B)
