Fruit weight has distributed weight of 480 grams SD of 14 grams. Heaviest 9% of fruit weigh how many grams

Answer 1

The heaviest 9% of the fruit, is the 91st percentile. The z-score for the 91st percentile is 1.34.

z score = x - mean / standard deviation, where x = weight

so 1.34 = (x - 480)/14

solve for x to get the weight for the 91st percentile.

The heaviest 9% of the fruit weight at least that amount.
