A simulated exercise gave n = 26 observations on escape time (sec) for oil workers, from which the sample mean and sample standard deviation are 371.84 and 24.38, respectively. Suppose the investigators had believed a prion that true average escape time would be at most 6 min. Does the data contradict this prior belief? Assuming normality, test the appropriate hypotheses using a significance level of 0.05. IN USE SALT State the appropriate hypotheses 0 Hz: }} = 360 Hiu > 360 Mo: M = 360 Ha u < 360 O Moid = 360 H: 360 0 Hp: } = 360 Haus 360 Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to three decimal places.) P-value = What can you conclude? O Do not reject the null hypothesis. There is sufficient evidence that true average escape time exceeds 6 min. Reject the null hypothesis. There is not sufficient evidence that true average escape time exceeds 6 min. O Do not reject the null hypothesis. There is not sufficient evidence that true average escape time exceeds 6 min. Reject the null hypothesis. There is sufficient evidence that true average escape time exceeds min.
