A particular fruit's weights are normally distributed, with a mean of 230 grams and a standard deviation of 37 grams. If you pick 81 fruit at random, what is the probability that their mean weight will be between 231 grams and 240 grams

0.3964

Step-by-step explanation:

Given: A particular fruit's weights are normally distributed, with a mean of 230 grams and a standard deviation of 37 grams.

Sample size : n= 87

Let be the sample mean.

The probability that their mean weight will be between 231 grams and 240 grams will be :

Hence, the required probability = 0.3964

1. 3
