Question Suppose X N(48, 7.5) and x = 33. Find and interpret the z-score of the standardized normal random variable. Select the correct answer below: This means that x=33 is two standard deviations (20) below or to the left of the mean, = 48. The value x=33 is two standard deviations (20) above or to the right of the mean, u=48. The value x=33 is one standard deviations (1a) above or to the right of the mean, = 48. The value x = 33 is one standard deviations (1a) below or to the left of the mean, u = 48.
