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. Current Method New Method Sample Size n1 41 n2 = 26 Sample Variance s 8 = 25 8=14 State the null and alternative hypotheses. Ho: 0 : Ho < a Calculate the value of the test statistic (to 2 decimals). The p-value is - Select your answer What is your conclusion? Use Table 4 of Appendix B. - Select your answer - that the population variances has decreased due to the lean process improvement
