14. Assume that the random variable X is normally distributed, with mean of 100 and standard deviation of 20. Compute the probability P(X> 116).

Z = (score-mean)/SD = (116-100)/20 = ?

Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability.
