Discuss the null hypothesis and the alternative hypothesis. State whether you are using a one- or two-tailed test and explain your reasoning.
Determine the appropriate hypothesis test to this problem. Justify your answer.
Conduct calculations “by hand” to compute the critical value and p-value of the test. Determine your decision using two methods, the rejection region and the p-value approach.
Use StatTools to conduct the hypothesis test. Copy and paste the command and output generated by StatTools.
