For the mower test data, what distribution might be appropriate to model the failure of an individual mower? What fraction of mowers fails the functional performance test using all the mower test data? What is the probability of observing x failures in the next 1 0 0 mowers tested, where x ranges from 0 to 2 0 ? Hint: You need to calculate and report the probabilities for all values of x from 0 to 2 0 not just a single value so I can see the likelihood of each specific outcome. What is the average blade weight and how much variability is occurring in the measurements of blade weights? Hint: Calculate the standard deviation and determine the upper and lower bounds that capture 9 5 % of the blade weights. Assuming that the data are normal, what is the probability that blade weights from this process will exceed 5 . 2 0 ? Assuming that the data are normal, what is the probability that blade weights will be less than 4 . 8 0 ? What is the actual percent of blade weights that exceed 5 . 2 0 or are less than 4 . 8 0
