All observations are used to construct the normal probability plot, and any observations above 0 may be outliers. B. All observations are used to construct the normal probability plot, and any observations that have a normal score greater than 2 in magnitude may be outliers. OC. All observations are used to construct the normal probability plot, and any observations that fall well outside the overall pattern of the data may be outliers. OD. All observations are used to construct the normal probability plot, and any observations that do not fall on a straight line may be outliers.
