The turkeys found in a county in southern Ohio have an average weight of 15.6 pounds with a standard deviation of 4.0 lbs. Forty-five turkeys are randomly selected for a county fair. What is the probabilty that the average weight of these turkeys is more than 18 pounds?
Use the information above to calculate the Z score. Round your calculation to the 2nd decimal place:
Now use the calculate Z score along with the Z table to find the probability that the turkeys' average weight is greater than 18 pounds:
Use the probability to answer the following question: Would it be unusual to randomly choose 45 turkeys and find that their average weight is more than 18 pounds?
