The following hypothesis test is to be conducted. H0: Median ≤ 150 Ha: Median > 150 A sample of 31 provided 23 observations greater than 150, 3 observations equal to 150, and 5 observations less than 150. Use Table 1 of Appendix B. What is the mean and standard deviation of the normal distribution that can be used for this statistical test (to 4 decimals if necessary)? Mean 13.5 Standard deviation 2.5981 What is the value of the test statistic (to 2 decimals)? -46.72; Use α = .01, what is the p-value (to 4 decimals)? 0.999 What is your conclusion? The population median is less than 150.
