The average height of an NBA player is 6.698 feet. A random sample of
30 players' heights from a major college basketball program found the
mean height was 6.75 feet with a standard deviation of 5.5 inches. At a =
0.05, is there sufficient evidence to conclude that the mean height differs
from 6.698 feet?
