Determine the decision criterion for rejecting the null hypothesis in the given hypothesis test; i.e., describe the values of the test statistic that would result in rejection of the null hypothesis. A store manager claims that the mean amount of time customers spend waiting in line is less than 3.7 minutes. You wish to test this claim at the 0.05 level of significance. The mean waiting time for a random sample of 56 customers is 3.5 minutes with a standard deviation of s = 1.2 minutes. What criterion would be used for rejecting the null hypothesis, that > 3.7? O Reject Ho if test statistic < -1.645. O Reject Ho if test statistic > 1.96 or < -1.96. O Reject Ho if test statistic < -1.96. O Reject Ho if test statistic < -1.673.
