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 = 22 Sample Variance 82 = 21 $7 = 14 State the null and alternative hypotheses. Ho : 07 5 Ha : 07 > Calculate the value of the test statistic (to 2 decimals). The p-value is between 0.10 and 0.20 . Use Table 4 of Appendix B. What is your conclusion? Do not conclude that the population variances has decreased due to the lean process improvement
