Answer:
16%
Step-by-step explanation:
Find the z-score.
z = (x − μ) / σ
z = (93 − 85) / 8
z = 1
This means 93 is one standard deviation above the mean.
According to the empirical rule, 68% of a normal distribution is between -1 and +1 standard deviations. So 32% is either less than -1 or greater than +1 standard deviations. Normal curves are symmetrical, so 16% is greater than +1 standard deviations.
