The mean weight of a breed of yearling cattle is 1179 pounds. Suppose that weights of all such
animals can be described by a Normal model with a standard deviation of 64 pounds.
8. Draw a graph displaying the empirical rule (68-95-99.7% rule).
9. How many standard deviations from the mean would a steer weighing 1000 pounds be?
10. How many standard deviations from the mean would a steer weighing 1500 pounds be?
11. What percentage of cattle would be less than 1179 pounds?
12. What percentage of cattle are between 1179 pounds and 1243 pounds?
13. Percentage between 1243 pounds and 1307 pounds?
14. What percentage of cattle are between 1115 and 1179 pounds?
15. What percentage of cattle are greater than 1115 pounds?
16. What percentage of cattle are less than 1115 pounds?
