The average height of US Adult males is 69.5 in.
and the standard deviation is 2.0. A
physician thinks that this national mean seems a little short for his patients,
so he records the height of the next 100 adult males to visit his office. Their average height is 69.75
in. If this physicianâ€™s
adult male patients are just a representative sample of nationwide adult males, what is the probability that his patients were so tall?
