A college-entrance exam is designed so that scores are normally distributed with a mean of 500 and a standard deviation of 100.
Debora [2.8K]

Answer:

68% of exam scores lie within one std. dev. of the mean

Step-by-step explanation:

Because the standard deviation is 100, one standard deviation above the mean comes out to 600.  Likewise, one std. dev. below the mean comes out to 400.  By the Empirical Rule, 68% of exam scores lie within one std. dev. of the mean.
