A very busy and fancy restaurant records the wait time for each customer that comes in. Below are 12 customers’ wait times (in minutes):
51 60 59 72 80 83 54 66 61 81 66 62
1.The manager wants to know if there is evidence that the true mean wait time is greater than 1 hour. What are the null and alternative hypotheses to test the claim? Will this be a one-sided or two-sided test?
2.Assuming that σ = 20 minutes, what is the test statistic for testing the hypotheses?
3.What is the corresponding p-value?
4.Do you reject the null hypothesis based on a significance level of .05? What conclusion should you tell the manager?

The average wait time to get seated at a popular restaurant in
the city on a Friday night is 10 minutes. Is the mean wait time
greater for men who wear a tie? Wait times for 12 randomly selected
men who were wearing a tie are shown below. Assume that the
distribution of the population is normal.

1. A company's customer support division wants to test to see if
wait time for a consumer to talk to a representative is under 10
minutes. The manager proposes to test one case where a
consumer was placed on hold. Is this a good testing
strategy? If not what would be a better testing
strategy? Could you form a Null Hypothesis or an
Alternative Hypothesis? If yes, what would they be?
