Question

A simulated exercise gave n = 29 observations on escape time (sec) for oil workers, from which the sample mean and sample standard deviation are 372.07 and 23.7, 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 0.05.
In USE SALT
State the appropriate hypotheses.
O Ho: H = 360
H: u < 360
O Ho: H = 360
H: us 360
O Ho: H = 360
H: u + 360
O Ho: H = 360
H: H > 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.)
