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 of27 drivers over the age of 60 and finds that the mean number of miles driven is 22.2. The population standard deviation is miles 3.7. At a=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 researcher claims that the average wind speed in his city is 10 miles per hour. In a random sample of 36 days, you found the average speed of wind is 10.2 with a standard deviation of 0.8 miles per hour. At α=0.05 is there enough evidence to say that the average is greater than the researcher’s claim. Show your work by using hypothesis testing.
