A particular fruit's weights are normally distributed, with a mean of 594 grams and a standard deviation of 16 grams.
If you pick a fruit at random, then 18% of the time, their mean weight will be greater than how many grams?
Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability (.18) and its Z score.
Z = (score-mean)/SD
