1.) According to the National Health and Nutrition Survey (NHANES), the mean height of males ages 20 and over is 69.2 inches. I randomly selected 35 golfers from the PGA Tour money list. Their average height was 71.3 inches with a standard deviation of 2.2 inches.

a.) At a ? = .05 significance level, can we conclude that on average Money List golfers are generally taller than the average male?

b.) Give a 95% confidence interval for the mean height of all golfers on the PGA Tour money list. Interpret your interval in context. Also give the margin of error.
