- Shorty’s Muffler advertises it can install a new muffler in 30
minutes. However, the work standards department at corporate
headquarters recently conducted a study and found that 25% of the
mufflers were not installed within 30 minutes or less. The Maumee
branch installed 50 mufflers last month. If the corporate report is
correct:
- How many of the installations at the Maumee branch would you expect to take more than 30 minutes?
- What is the likelihood that fewer than 10 installations took more than 30 minutes?
- What is the likelihood that 10 or fewer installations took more than 30 minutes?
- What is the likelihood that exactly 10 of the 50 installations took more than 30 minutes?

Setting Standards, Materials and Labor Variances Tom Belford and Tony Sorrentino own a small business devoted to kitchen and bath granite installations.
