– Determine the direction of the hypothesis test (one-sided left, one-sided right, bidirectional)
– Determine the test statistic (z* or t*) and the p-value for each of the following situations and
– Determine if they would cause the rejection of the null hypothesis if the confidence level was set
at 95% in each case. (Hint: be wary of the sample size)
