A study conducted by Hershey’s discovered that Americans consumed an average of 11.4 pounds of chocolate per year (seems low to me). Let’s assume that the annual chocolate consumption follows the normal distribution with a standard deviation of 3.6 pounds.

a. What is the probability that I will consume 1. less than 7 lbs of chocolate next year?

2. more than 9 lbs of chocolate next year?

3. between 8 and 12 lbs of chocolate next year?

4. exactly 10 lbs of chocolate next year?

b. What is the annual consumption of chocolate that represents the 60th percentile?
