SpletSolution: 132 – 100 = 32, which is 2 (16). As such, 132 is 2 standard deviations to the right of the mean. 100 – 68 = 32, which is 2 (16). This means that a score of 68 is 2 standard deviations to the left of the mean. Since 68 to 132 is within 2 standard deviations of the mean, 95% of the exam participants achieved a score of between 68 and 132.

SpletGiven a normal distribution with a mean of M = 100 and a standard deviation of S = 15, we calculate a value of M + S = 100 + 15 = 115 is one standard deviation above the mean.
