Elizabeth Burke has asked you to analyze the functional test performance in the Mower Test worksheet and the Blade Weight worksheet in the Performance Lawn Equipment Database.

1. What distribution might be appropriate to model the failure of an individual mower for the mower test data?
2. What fraction of mowers fails the functional performance test using all the mower test data?
3. What is the probability of having x failures in the next 100 mowers tested, for x from 0 to 20?
4. What is the average blade weight, and how much variability is occurring in the measurements of blade weights?
5. Assuming that the data are normal, what is the probability that blade weights from this process will exceed 5.20?
6. What is the probability that blade weights will be less than 4.80?
7. What is the actual percent of blade weights that exceed 5.20 or are less than 4.80 from the data in the worksheet?
8. Is the process that makes the blades stable over time? That is, are there any apparent changes in the pattern of the blade weights?
9. Could any of the blade weights be considered outliers?
10. Is the assumption that blade weights are normally distributed justified?
