2. (This problem is required to submit) The variance in a production process is an important measure of the quality of the process. A large variance often signals an opportunity for improvement in the process by finding ways to reduce the process variance. a. Conduct a statistical hypothesis test to determine whether there is a significant difference between the variances in the bag weights for two machines. (30%) b. Use a 0.05 level of significance and the p-value approach. What is your conclusion? Which machine, if either, provides the greater opportunity for quality improvements?
