The scores on a quiz are normally distributed. the mean of the quiz is 93 and the standard deviation is 4.2. by using the empirical rule, what scores fall 1 standard deviation from the mean? 89 and 101 84.6 and 101.4 89.2 and 96.8 88.8 and 97.2

any score that lies between 88.8 and 97.2 is within one std. dev. of the mean

Step-by-step explanation:

One std. dev. above the mean would be 93 + 4.2, or 97.2.  One std. dev. below the mean would be 93 - 4.2, or 88.8.

So:  any score that lies between 88.8 and 97.2 is within one std. dev. of the mean.
