Question 424703: The diameter of grapefruit in a certain orchard are normally distributed with a mean of 5.73 and a standard deviation of 0.48 inches.show all work.
What % of the grapefruit in this orchard is larger than 5.93?
A random sample of 100 grapefruit is gathered and the mean diameter is calculated. What is the probability that the sample mean is greater than 5.93?
Thank You

The diameter of grapefruit in a certain orchard are normally distributed with a mean of 5.73 and a standard deviation of 0.48 inches.show all work.
What % of the grapefruit in this orchard is larger than 5.93?
------
z(5.93) = (5.93-5.73)/0.48 = 0.4167
P(x > 5.93) = P(z > 0.4167) = 0.3385
===============================================
A random sample of 100 grapefruit is gathered and the mean diameter is calculated. What is the probability that the sample mean is greater than 5.93?
-----
z(5.93) = (5.93-5.73)/[0.48/sqrt(100)] = 4.167
---
P(x-bar > 5.93) = P(z > 4.1667) = 0.00001546..
