Question 2

According to statistical data, the average walking speed of a human is 3.5 miles per hour. Suppose that a researcher is conducting a study to see if the average walking speed of the Humber College gym goers is not significantly different. The researcher works with a sample of 41 Humber College gym goers. The null and alternative hypotheses are H0: p = 3.5 (claim) H1: u = 3.5 For a 0.040 level of significance, the researcher finds the critical value(s) ta. 2 it% = $2.123 a. If the test statistic equals tst = 1.4, select the sketch with the most appropriate rejection region and test statistic. \fb. Does the test statistic fall inside the rejection region? '2 c. What is the short version of researcher's conclusion (in terms of H0 and H1)? -" Reject H0 (claim) and support H1 -"' Fail to support H0 (claim) and reject H1 Reject H0 (claim) and fail to support H1 Fail to reject H0 (claim) and fail to support H1 \"" Support Hg (claim) and support H1
