A Simulated Exercise Gave N 24 Observations On Escape Time Sec For Oil Workers From Which The Sample Mean And Sampl 1 (88.92 KiB) Viewed 85 times

A simulated exercise gave n = 24 observations on escape time (sec) for oil workers, from which the sample mean and sample standard deviation are 367.19 and 22.34, respectively. Suppose the investigators had believed a priori 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 .05. (Give t to 2 decimal places and the p-value to 3 decimal places.) t = P-value = Conclusion O Reject the null hypothesis, there is significant evidence that true average escape time exceeds 6 min. O Reject the null hypothesis, there is not significant evidence that true average escape time exceeds 6 min. Fail to reject the null hypothesis, there is not significant evidence that true average escape time exceeds 6 min. O Fail to reject the null hypothesis, there is significant evidence that true average escape time exceeds 6 min.
