Use the given data values (a sample of female arm circumferences in centimeters) ta 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 quaniile plot, then determine whether the data appear ta be from a population with a normal distribution.

Sample data for the arrival delay times (in minutes) of airlines flights is given below. Determine whether they appear to be from a population with a normal distribution. Assume that this requirement is
loose in the sense that the population distribution need not be exactly normal, but it must be a distribution that is roughly bell-shaped.

Is the requirement of a normal distribution satisfied?
( A. Yes, because the histogram of the data 1s not bell shaped, there is more than one outlier, and the points in the narmal quantile plot do not lie reasonably close to a straight line.
‘> B. No, because the histogram of the data is not bell shaped, there is more than one outlier, and the points in the normal quantile plot do not lie reasonably close to a straight line.
7“ C. No. because the histogram of the data is bell shaped, there are less than two outliers, and the points in the normal quantile plot lie reasonably close to a straight line.
(— D. Yes, because the histogram of the data is bell shaped, there are less than two outliers, and the points in the normal quantile plot lie reasonably close to a straight line.
