Q7. During recent seasons, Major League Baseball has been criticized for the length of the
games. A report indicated that the average game lasts 3 hours and 30 minutes. A sample
of 17 games revealed the following times to completion. (Note that the minutes have
been changed to fractions of hours, so that a game that lasted 2 hours and 24 minutes
is reported at 2.40 hours.)
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, five years ago and now. The information is reported below. Is it
reasonable to conclude the percent is less now than five years ago?
