Use the accompanving table of standard scores and their percentles under the normal distribution to find the approximate standard score of the following data values. Then state the approximate number of standard deviations that the value les above or below the mean. (Hint: Look for the percentile value that is dosest to the given value and use the corresponding z-score as an approximation. Ifa percentile lies haltway between two percentiles in the table, take the averane of the corresponding z-scores.) a. A data value in the 90th percentile b.
