Chapter 3, Problem 3.15P
Professional athletes are threatening to strike because they claim that they are underpaid. The team owners have released a statement that says, in part, “The average salary for players was $1.2 million last year.” The players counter by issuing their own statement that says, in part, “The typical player earned only $753,000 last year.” Is either side necessarily lying? If you were a sports reporter and had just read Chapter 3 of this text, what questions would you ask about these statistics?

Helen Hutchins and Greg Haglund took the elevator together to the fourth-floor meeting room, where they were scheduled to meet the rest of the market research team at the Franklin Company. On the way up, Helen mentioned that she had terminated her contract for the land-line telephone in her apartment and was going to be using her cell phone exclusively to save money. “I rarely use my house phone anymore and about the only calls I get are from organizations wanting donations or doing surveys,” she said. Greg said that he and his wife were thinking about doing the same thing. As Helen and Greg walked toward the meeting room, Helen suddenly stopped. “If everyone did what I am doing, wouldn’t that affect our marketing research telephone surveys?” she asked. “I mean, when we make calls the numbers are all to land-line phones. Won’t we be missing out on some people we should be talking to when we do our surveys?” Helen continued. Greg indicated that it could be a problem if very many people…

The respondents were classified according to whether they currently had a child studying in a school of management and whether they thought that the loan burden for most management students is too high, right amount, or too little.

- Answer the following question in 5-6 sentences. What are the pros and cons of a large current account deficit? What can the government do to reduce a current account deficit? For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).arrow_forwardn an unsolved airplane hijacking case from 1971, the hijacker (given the alias of D. B. Cooper) parachuted out of the back of a Northwest Boeing 727 over the southwest part of Washington State with $200,000 in $20 bills strapped to his body. The money and four parachutes had been provided by the FBI after Cooper took over the plane, claiming to have a bomb. Despite an intensive search by the FBI and 400 troops from Fort Lewis near the projected landing spot, Cooper was never found and his fate remains unknown. The combined weight of Cooper, the money, and his parachutes was approximately 230 lbs. He jumped from an altitude of 10,000 feet. Assume a linear drag term of −cv (where c is the drag coefficient and v is the velocity), and assume that he opened his parachute instantaneously 30 seconds after he stepped out of the plane and that his drag coefficient was c = 1.1 lbs-sec/ft before the chute opened and c = 12 lbs-sec/ft after. Estimate the speed (in ft/s) with which he hit the…arrow_forwardIn a murder trial in Los Angeles, the prosecution claims that the defendant was cut on the left middle finger at the murder scene, but the defendant claims the cut occurred in Chicago, the day after the murders had been committed. Because the defendant is a sports celebrity, many people noticed him before he reached Chicago. Twenty-two people saw him casually, one person on the plane to Chicago carefully studied his hands looking for a championship ring, and another person stood with him as he signed autographs and drove him from the airport to the hotel. None of these 24 people saw a cut on the defendant’s finger. If in fact he was not cut at all, it would be extremely unlikely that he left blood at the murder scene. (a) Because a person casually meeting the defendant would not be looking for a cut, assume that the probability is .9 that such a person would not have seen the cut, even if it was there. Furthermore, assume that the person who carefully looked at the…arrow_forward
