Find that the sample mean is 78 strokes with a sample

Reference no: EM13196979

Melvin says his average golf score is 75. Melvin lies a lot, and you claim his average score is higher than 75. So, you observe his game for a random sample of ten rounds and find that the sample mean is 78 strokes with a sample standard deviation of 4 strokes. At the .05 level should you believe Melvin or have him barred from the country club?
