I believe that the number of times a person will yawn in a day is normally distributed, with a standard deviation of 3. If I do a study of 36 random individuals, and they have an average of 12 daily yawns with a standard deviation of 3.6, find a 99% confidence interval for the standard deviation in the number of daily yawns for the population of all people.

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...
