An airline offers discounted "advance-purchase" fares to customers who buy tickets more than 30 days before travel and charges "regular" fares for tickets purchased during those last 30 days. The company has noticed that 50% of its customers take advantage of the advance-purchase fares. The "no-show" rate among people who paid regular fares is 30%, but only 5% of customers with advance-purchase tickets are no-shows. Complete parts a through c below. a) What percent of all ticket holders are no-shows? The percentage is %. (Type an integer or a decimal. Do not round.) b) What's the probability that a customer who didn't show had an advance-purchase ticket? The probability is (Round to four decimal places as needed.) c) Is being a no-show independent of the type of ticket a passenger holds? Explain. Choose the correct answer below. O A. No, because a passenger may have both types of tickets. O B. No, because the likelihood of being a no-show is different for each type of passenger. OC. Yes, because the likelihood of being a no-show is identical for both types of passengers. O D. Yes, because each passenger can only have an advance-purchase or regular purchase ticket.

. In 2010, of a total of 67,000 rooms on the Las Vegas Strip, Caesars Entertainment managed 22,880, while MGM Resorts managed over 12,000. However, owing to the Great Recession and new hotel openings, between 2008 and 2010, MGM's hotel occupancy decreased from 92% to 89%, while its average daily room rate fell from $148 to $108. Meanwhile, CityCenter, managed by MGM Resorts, and the Cosmopolitan opened with 4,000 and 3,000 rooms respectively, and the 1,720-room Sahara closed. (Sources: Caesars Entertainment Corp., Annual Report 2010; MGM Resorts, Annual Report 2010; "Sahara's closure on May 16 will mark `the end of an era'," Las Vegas Sun, March 11, 2011.) (a) Using a suitable figure, explain how the opening of CityCenter and the Cosmopolitan affects the residual demand for an existing hotel and how it should adjust prices.

Use four decimals in your answers. (a) What is the probability that a prisoner escaping from this provincial prison is not captured? 0.65 (b) What is the probability that a captured prisoner used road A in their escape attempt?

Mateo believes that completely cutting caffeine out of a person's diet will allow them more restful sleep at night. He randomly selects 8 adults to help him test this theory. Each person is asked to consume two caffeinated beverages per day for 28 days and then cut back to no caffeinated bevarages for an additional 28 days. During each period, the participants record the number of nights of restful sleep that they had. The following table gives the results of the study. Test Mateo's claim at the 0.05 level of significance. Give answers to 4 decimal places as needed.

To receive a particular professional designation, an individual must pass a specific professional exam. A preparatory course is available, and individuals who take the preparatory course, pass the professional exam 90% of the time, while individuals who do not take the preparatory course only pass the exam 20% of the time. Suppose 55% of individuals who take the professional exam have taken the preparatory course. What percent of individuals who take this exam pass? The percent of individuals passing is percent. Do NOT use the % sign as part of your answer, and do NOT round your answer.
The past records of a supermarket show that its customers spend an average of $110 per visit at this store. Recently the management of the store initiated a promotional campaign according to which each customer receives points based on the total money spent at the store, and these points can be used to buy products at the store. The management expects that as a result of this campaign, the customers should be encouraged to spend more money at the store. To check whether this is true, the manager of the store took a sample of 14 customers who visited the store. The following data give the money (in dollars) spent by these customers at this supermarket during their visits. 106.13 107.43 124.68 124.88 101.17 72.75 85.45 86.05 100.4 98.84 101.63 95.56 89.40 119.52 Assume that the money spent by all customers at this supermarket has a normal distribution.

The Conch Café, located in Gulf Shores, Alabama, features casual lunches with a great view of the Gulf of Mexico. To accommodate the increase in business during the summer vacation season, Fuzzy Conch, the owner, hires a large number of servers as seasonal help. When he interviews a prospective server, he would like to provide data on the amount a server can earn in tips. He believes that the amount of the bill and the number of diners are both related to the amount of the tip. He gathered the following sample information.
