Recall that the standard normal random variable z represents the number of standard deviations a value x is away from the mean The normal probability table gives area under the curve to the left of a given z value also called the cumulative probability Use the table to find the value of zo corresponding to a 0 80 cumulative probability rounding the result to two decimal places P z Szo 0 80 Zo
