Chapter 7, Problem 24P
Gabrielle Kramer, owner of Pet Paradise, is opening a new store in Columbus, Ohio. Her major concern is the hiring of a manager and several associates who are animal lovers. She also has to coordinate the renovation of a building that was previously owned by a chic clothing store. Kramer has gathered the data shown in Table 7.14.
- How long is the project expected to take?
- Suppose that Kramer has a personal goal of completing the project in 14 weeks. What is the probability that it will happen this quickly?
