Extracted text: 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 apprópriate hypothesis test. Current Method New Method Sample Size n = 41 n = 20 Sample Variance = 21 = 11 %3D State the null and alternative hypotheses. Họ : o H : o > Calculate the value of the test statistic (to 2 decimals). The p-value is greater than 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.
