Hint(s) Check My Work 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 = 26 n2 = 26 Sample Variance s = 28 s; = 13 State the null and alternative hypotheses. Ho : o s H, : o> Calculate the value of the test statistic (to 2 decimals).
