 A leading magazine (link Barron's) reported at one time that the average number of weeks an individual is unemployed is 29 weeks. Assume that the length of unemployment is normally distributed with a population mean of 29 weeks and the population standard derivation of 4 weeks. Suppose you would like to select a random sample of 16 unemployed individuals for a follow-up study. Round the answers of the following questions to 4 decimal places.

1. What is the distribution of XX? XX-N(,)

2. What is the distribution of "xx"? "xx"-N(,)

3. What is the probability that one randomly selected individual found a job for more than 27 weeks?

The queue manager at a bank believes that their clients spend, on average, less than 15 minutes in the queue. To test his belief the manager commissioned a study, which found out that, from a random sample of 80 customers, the average waiting time was 18 minutes. Assume a population standard deviation of 3 minutes and that the waiting time is approximately normally distributed.
(a) Formulate the null and the alternative hypothesis for this test situation. 
(b) Which test statistic (z or t) is appropriate for this test? Give a reason for your answer. 
(c) Conduct a hypothesis test for a single mean at 5% significance level. Interpret your results

You are studying the affect of financial means on students' average hours of sleep. You have found a reliable study indicating that students that have a job and do not receive financial support from their parents or guardians sleep an average of 5.8 hours per night (excluding weekends) on average (population average).
You decide to test whether or not students who do not work get more sleep per week night on average. You take a sample of 63 students that do not work and live with parents or guardians then you record the number of hours per week night they sleep for a period of 15 weeks (1 semester). You find that the average (mean) hours slept per week night in your sample is 7.2 hours and the standard deviation is 3.9 hours. Assume that average sleeping hours on week nights is normally distributed across students.
 
Remember to define the null and alternative hypotheses to help you answer the question.
 
What will the value of the test statistic (z-test) be?
(Round your answer to two decimal places)
