In an effort to make better use of its resources, the New York City Food Bank engaged in lean process improvement. This employee-driven kaizer effort resulted in a new method for packing meals for distribution to needy families. One goal of the process improvement effort was to reduce the variability in the meal-packing time. The following table summarizes information from a sample of data using the current method and the new method. Did the kaizen event successfully reduce the population variation? Use a = 0.10 and formulate the appropriate hypothesis test. Sample Size Sample Variance State the null and alternative hypotheses. Hoo-Select your answer - H₂o-Select your answer Calculate the value of the test statistic (to 2 decimals). Current Method The p-value is Select your answer - V Use Table 4 of Appendix B.
