Question

In the professional football business, it is accepted dogma that players will perform better if they are intelligent. Before players are drafted, they are asked to complete an intelligence test. These IQ tests often have a standardized mean of 100 and a standard deviation of 15. Based on this information, use the Empirical Rule to answer the following question: If 348 players are drafted, approximately how many of the drafted players will have IQs that fall within one standard deviation of the mean (ignore the fact that some but not all of them might have a college degree)?

Explanation / Answer

By Empirical rule, 68% of the drafted players will have IQs that fall within one standard deviation of the mean.

Ans : 68% of 348 = 0.68*348 =236.64 = 237
