Question
In a simulated exercise, there were \( n = 28 \) observations on escape time (seconds) for oil workers. The sample mean and sample standard deviation are 372.76 and 22.85, respectively. Suppose the investigators had believed a priori that the true average escape time would be at most 6 minutes. Does the data contradict this prior belief? Assuming normality, test the appropriate hypotheses using a significance level of 0.05.
