Chapter 1, Problem 33SE(choose chapter or problem)
A personnel manager for a certain industry has records of the number of employees absent

are many days with zero, one, or two absent and only a few with more than ten absent, the

least 75% of these values lie. Use the result in Exercise 1.32 to find such an interval.
