According to the U.S National Center for Health Statistics, the mean height for adult American males is mu = 65.5 inches. Assume the heights are normally distributed with standard deviation of sigma = 3.2. You may use StatCrunch for showing work, showing sketches and making calculations
Determine the probability of finding an adult American male that is:
a) Less than or equal to 68.7 inches tall. (Show work with a sketch).
b) More than or equal to 68.7inches tall.
c) How tall must an adult American male be to be in the top 10% of the adult American male population? (Show work with a sketch).
The solution discusses hypothesis testing regarding American male height.
