# Statistics

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?

1. 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)
