Question

The weight of a specific type of male monkey is normally distributed with a mean of 15 pounds and a standard deviation of 3 pounds. What is the score for a monkey weighing 19 pounds?​

Answer 1

1.33

Explanation:

The z-score of a value is found by subtracting the mean from the value and then dividing by the standard deviation, this is the formula for the z-score.

z-score = (19-15)/3

z-score = 4/3

z-score = 1.33

The z-score for the monkey is about 1.33
