Daily Driving The average number of miles a person drives per day is 24 . A researcher wishes to see if people over age 60 drive less than 24  miles per day. She selects a random sample of 32 drivers over the age of  60 and finds that the mean number of miles driven is 22.9. The population standard deviation is 3.1miles. At α=0.05, is there sufficient evidence that those drivers over 60 years old drive less than 24 miles per day on average? Assume that the variable is normally distributed. Use the  P-value method with a graphing calculator.   a)Find the P-value. Round the answer to at least four decimal places.
