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. 1075 1077 957 1026 List the z scores for the normal quantile plot. 1077 ... 1443 1073 1049 (Round to two decimal places as needed. Use ascending order.) Identify the coordinates of each point in the normal quantile plot. Use ordered pairs of the form (x,y), where x is the sorted human brain volumes, and y is the corresponding z score.

OA. No, but the points in the normal quantile plot lie reasonably close to a straight line and show some
systematic pattern that is a straight line pattern.
OB. Yes, but the points in the normal quantile plot do not lie reasonably close to a straight line or show a
systematic pattern that is a straight line pattern.
OC. Yes, because the pattern of the points in the normal quantile plot is reasonably close to a straight line.
OD. No, because the points in the normal quantile plot do not lie reasonably close to a straight line or show a
systematic pattern that is a straight line pattern.
