A sample of human brain volumes ​(cm3​) is given below. Use the given data values to identify the corresponding z scores that are used for a normal quantile​ plot, then identify the coordinates of each point in the normal quantile plot. Construct the normal quantile​ plot, then determine whether the data appear to be from a population with a normal distribution. 1067 1075 955 1415 1075 1050 1072 1033

Expert Solution

The given data is not from normal distribution. If the sample data comes from a normally distributed population then the normal probability plot should look like a 45o line, with random variations about it. If that is not the case, and the pattern of the normal probability plot departs significantly from the normal probability plot, then one should suspect that the distribution is not normal.
