Most binomial probability calculations required in these exercises can be done by using Table C or the Normal approximation. Your instructor may request that you use the binomial probability formula or software. In exercises requiring the Normal approximation, you should use the continuity correction if you studied that topic.

Question 5.32

5.32 Finding .

In Example 5.5, we found when has a distribution. Suppose we wish to find using the Normal approximation.

  1. What is the value for if the Normal approximation is used without continuity correction?
  2. What is the value for if the Normal approximation is used now with continuity correction?
