In an effort to make better use of its resources, the New York City Food Bank engaged in lean process improvement. This employee-driven kaizen 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 of H₁: o> of Calculate the value of the test statistic (to 2 decimals). The p-value is greater than 0.20 What is your conclusion? Current Method Do not conclude improvement. 7=41 =21 Use Table 4 of Appendix B. New Method ny=20 that the population variances has decreased due to the lean process
