P-Value Method
Insurance companies partially base automobile insurance
rates on the mileage per year of the insured car. The average passenger vehicle
in the United States is driven 11.3 thousand miles per year. In a Florida town,
the average of 42 residents is found to be 9.8 thousand miles per year with a
standard deviation of 5.8 thousand miles. It is claimed that the driving habits
of these residents are different from the rest of the country. Is this claim
supported at the 2% level of significance? Assume a normal population. Use the
P-value method.
