Given that the mean score is 76 and standard deviation is 14. Consider, μ-2σ=76-(14*2) =48 Hence, the score 48 represents the two standards below the mean. From the empirical rule, 95% of the data values lies between the two standard deviations from the mean, 2.5% of the data values below the two standard deviations and 2.5% of the values above the two standard deviations. Therefore, the approximate percentage of students who scored less than 48 on the test is 2.5%.
