Use the given data values (height in inches of players in the starting lineup of a particular basketball team) and identify the corresponding z scores that are used for a normal quantile plot, then construct the normal quantile plot and determine whether the data appear to be from a population with a normal distribution.
Given 82, 80, 86, 75, 77, the mean is given by (82 + 80 + 86 + 75 + 77) / 5 = 80
It can be noticed that the pattern of the given points are reasonable close to a straight line.
Therefore, the data come from a normally distributed population because the pattern of the given points are reasonable close to a straight line.
