Transcribed Image 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 α = 0.10 and formulate the appropriate hypothesis test.
Sample Size
Sample Variance
State the null and alternative hypotheses.
Hoo-Select your answer - 02
H₂: of - Select your answer 02
Calculate the value of the test statistic (to 2 decimals).
Current Method
n1= 26
$ = 23
New Method
n₂ = 27
s² = 11
The p-value is Select your answer - V Use Table 4 of Appendix B.
What is your conclusion?
Select your answer that the population variances has decreased due to the lean process improvement.
