Benjamin randomly surveys guests who visited the aquarium in the past week and receives 28 responses. He calculates a sample mean of 137 minutes with a sample standard deviation of 3.5 minutes. Conduct a significance test using a significance level of ? = 0.01 for the mean and make a conclusion.4.536 > 2.771; Benjamin rejects the null hypothesis. The data suggests that the mean time for guests is mot 134 minutes over the past week.4.454 > 2.771; Benjamin rejects the pull hypothesis.
