13.A variable is normally distributed with a mean of 5.00 and a variance of 4.00. Calculate the probability of observing a value of negative 0.40 or less. That is, calculate P (Xi ≤ –0.40) given X is distributed as N(5, 4). Use this excerpt from the cumulative distribution function for the standard normal random variable table to calculate your answer. The calculated value is closest to:A:A.0.35%. B:B.0.62%. C:C.8.85%. |
