- 2. Sarah is a newly recruited revenue manager of Rose hotel that is a 300-room family owned hotel in Pasadena, California. She is the head of the reservation department with two reservation staff members. She is also in charge of pricing, inventory allocation and other booking issues. It is important to calculate the anticipation of no-shows so that Sarah can decide number of overbookings to accept. If a hotel can estimate the most accurate number of no show and set its overbooking level at that number, it will be able to achieve the highest revenue possible by making sure all the rooms go occupied.

- The Los Angeles City Controller's office calculated that in 2013, the city employed 47030 full-time employees and 10142 part-time employees. Assume that an outside advocacy group had been lobbying the Mayor's office to convert part-time workers into full-time workers throughout 2014. The Controller's office makes its calculations annually. Suppose that the outside advocacy group wanted to know the proportion of city employees (excluding per-event employees) who are full-time employees p in June 2014 to gauge if their lobbying efforts had been effective. Suppose that the group surveyed a random sample of 1000 city employees (excluding per-event employees) in June 2014 and found that 845 were full-time employees and 155 were part-time employees. If the advocacy group planned to use a one-sample z-test for a proportion to test their lobbying eforts, the appropriate null hypothesis would be and the appropriate alternative hypothesis would beA new chart set to be released later today by the Republican side of the Senate Budget Committee detais a starting statistic: "Over 100 Milion People in U.S. Now Receiving S Some Form Of Federal Weifare.
