Probability theory is a branch of mathematics that deals with the subject of probability. Although there are many different concepts of probability, probability theory expresses the definition mathematically through a series of axioms. Usually, these axi…

The college graduates of 2000 could hardly have asked for better luck. The unemployment rate dropped to 4.1 % in May 2000- roughly, the lowest level in a generation- and employers were literally scrambling for new hires. Starting salaries rose, many graduating seniors had numerous job offers, and some firms even offered $10,000- $20,000 bonuses to students who signed the dotted line. Three years later, the job market for the Class of 2003 was rather different. U.S. economic growth had slowed to a crawl, and then to a halt. Companies that had stocked up on recent college grads in the tighter labour markets of 1998-2000 found themselves with more than they knew what to do with in 2002 and 2003. They were not eager to hire more. Bonuses and other “perks” disappeared; job offers became scarcer. With the unemployment rate around 6% in May and June of 2003, the job market was far from the worst ever. But it was nothing like the glory days of 2000. YOU ARE REQUIRED TO: (iv) Briefly…

A radio talk show host with a large audience is interested in the proportion of adults in his listening area that think the drinking age should be lowered to 18. To find out, he poses the following question to his listeners: “Do you think that the drinking age should be reduced to 18 in light of the fact that 18-year-olds are eligible for military service?” He asks listeners to phone in and vote “yes” if they agree the drinking age should be lowered and “no” if not. Reference: Ref 12-4 You are told that the sample proportion of those who phoned in and answered yes is = 0.70 and the standard error of the sample proportion is 0.0459. The number of people who phoned in Select one: a. is 21. b. is 50. c. is 100. d. is 200. e. cannot be determined from the information given.

For the time being, the air traffic control system in the United States is run by the federal government. Several groups disagree with this and would like to privatize the air traffic control system. Among the arguments given for privatization is that flight delays are much too common in the United States. A first step in deciding if, indeed, delays in the U.S. are "too common" might be to compare the flight delay information from the U.S. and other nations. You have in front of you the following chart, which summarizes the information from three samples of flights from the past six weeks. One of the samples is composed of domestic U.S. flights, one is composed of domestic Canadian flights, and one is composed of domestic British flights. The information recorded for each flight is the time (in minutes) that the plane was late to the arrival gate. (If the plane was early, the time recorded was negative.)
