A particular fruit's weights are normally distributed, with a mean of 764 grams and a standard deviation of 33 grams.
The heaviest 15% of fruits weigh more than how many grams?
Give your answer to the nearest gram.
the upper 15% of weights are a little over one S.D. above the mean
so, more than ... 764 + 33
using a z-score table ... 1.036 S.D
so, more than ... 764 + (33 * 1.036)
