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. Sample Size Sample Variance State the null and alternative hypotheses. Hoo of H₁: o> of Calculate the value of the test statistic (to 2 decimals). The p-value is greater than 0.20 What is your conclusion? Current Method Do not conclude improvement. 7=41 =21 Use Table 4 of Appendix B. New Method ny=20 that the population variances has decreased due to the lean process

pls help ASAP.

Mr. Jones has a penny jar. He places pennies in his jar every day at the samerate. Pretend there are 58 pennies in the jar on day 14.a) Sam thinks 30 + 2D= T (where D is the number of days and T is the totalin the jar) might be Mr. Jones’s penny jar. Would Sam’s formula fit Mr.Jones’ penny jar? (explain)

-5V12x +17 b. 621x - 14 + 8 = 5 a. 2. Show how to solve the equation. Remember to check for extraneous solutions x - 5 = V10 - 2x

this is all that is given, i need help please and thank you
