An improvement to the production process has been implemented, and, hopefully, there will be a change from the historical defective distribution: π1 = .80, π2 = .10, π3 = .05, π4 = .03, and π5 = .02. A random sample of 300 motorcycles produced under the new system is classified as follows:
At the a = .05 level, does there appear to be a change in the historical proportions of defectives?
