Consider the following hypothesis test: h0: u u is less than or equal to 50ha: u > 50a sample of 60 is used and the population standard deviation is 8. use the critical value approach to state your conclusion for each of the following sample results. use = .05.a. with ? ? x = 52.5, what is the value of the test statistic (to 2 decimals)? can it be concluded that the population mean is greater than 50? b. with ? x? = 51, what is the value of the test statistic (to 2 decimals)? can it be concluded that the population mean is greater than 50? c. with ? x? = 51.8, what is the value of the test statistic (to 2 decimals)? can it be concluded that the population mean is greater than 50?
