Alarge number of applicants for admission to graduate study in business are given an aptitude test. scores are normally distributed with a mean of 460 and standard deviation of 80. what fraction of the applicants would you expect to have a score of 400 or above?

The fraction or percentage of the applicants that we would expect to have a score of 400 or above is 77.34%

Step-by-step explanation:

Scores are normally distributed with a mean of 460 and a standard deviation of 80. For a value x, the associated z-score is computed as , therefore, the z-score for 400 is given by . To compute the fraction of the applicants that we would expect to have a score of 400 or above, we should compute the probability P(Z > -0.75) = 0.7734, i.e., the fraction or percentage of the applicants that we would expect to have a score of 400 or above is 77.34%
