QUESTION 8
Assume the weights of Farmer Carl's potatoes are normally distributed with a mean of 9.0 ounces and a standard
deviation of 1.1 ounces. He bags his potatoes in groups of 6. You buy a bag and the total weight is 48 ounces. Here we
determine how lucky or unlucky you are.
(a) What is the mean potato weight in your bag of 6? Enter your answer to 1 decimal place.
(b) If 6 potatoes are randomly selected, find the probability that the mean weight is less than the mean found in
your bag. Round your answer to 4 decimal places.
(c) Which statement best describes your situation? Choose a,b,c or d
a. You got extremely unlucky because the probability of getting a bag weighing less than yours is about 0.01%.
b. This is not particularly unusual because the mean weight in your bag is only 1 ounce below the mean of all Carl's potatoes.
c. This is an unusually small amount of potatoes. You are unlucky because the probability of getting a bag weighing less than
yours is only about 1.3%.
d. You got lucky with such a generous amount of potato your bag.
