In the July 2005 issue of a particular magazine, a special advertising section focused on private jets. Included in the section was an article about "fractional" jet ownership, in which wealthy individuals and companies share ownership in private
jets. The idea is that the expensive airplanes can be better utilized if more than one individual or company has an ownership stake. Data were collected which show the number of fractional ownerships since 1986. Using these data, develop a line
chart that displays the trend in fractional ownership between 1986 and 2004.

- The amount of income spent on housing is an important component of the cost of living. The total costs of housing for homeowners might include mortgage payments, property taxes, and utility costs (water, heat, electricity). An economist selected a sample of 20 homeowners in New England and then calculated these total housing costs as a percent of monthly income, 5 years ago and now. The information is reported below.

On January 31, 2006, 9 of the 30 stocks making up the DJIA increased in price (The Wall Street Journal, February 1, 2006). On the basis of this fact, a financial analyst says that maybe we can assume that 30% of the stocks traded on the New York Stock Exchange (NYSE) went up the same day. You have decided to do your own test. A sample of 78 stocks traded on the NYSE that day showed that 15 went up.
