Problem
Whole Life Organic, Inc., produces high-quality organic frozen turkeys for distribution in organic food markets in the upper Midwest. The company has developed a range feeding program with organic grain supplements to produce their product. The mean Weight of its frozen turkeys is 15 pounds with a variance of 4 . Historical experience indicates that weights can be approximated by the normal probability distribution. Market research indicates that sales for frozen turkeys over 18 pounds are limited. What percentage of the company's turkey units will be over 18 pounds?
Solution
Step 1 ：\(Z = \frac{X - \mu}{\sigma}\)
Step 2 ：\(Z = \frac{18 - 15}{2}\)
Step 3 ：\(P(X > 18) = P(Z > 1.5)\)
