Finish up The variance in a production process is an important measure of the quality of the process. A large variance often signals an opportunity for improvement in the process by finding ways to reduce s process variance. Jelly Belly Candy Company is testing two machines that use different technologies to fill three pound bags of jelly beans. The following tables contain a sample of data on the wel of bags (in pounds) filled by each machine. Machine 1 Machine 2 2.95 3.45 3.50 3.75 3.48 3.26, 3.33 3.20 3.22 3.30 3.34 3.28 3.29 3.25 3.30 3.26 3.16 3.20 3.22 3.38 3.90 3.36 3.25 3.28 3.39 3.34 3.35 3.19 3.35 3.05 3.36 3.28 3.20 3.22 2.98 3.45 3.70 3.34 3.18 3.35 3.30 3.28 3.30 3.20 3.16 3.33 3.12 Conduct a statistical test to determine whether there is a significant difference between the variances in the bag weights for two machines. Use a 0.05 level of significance. What is your conclusion? State the null and alternative hypotheses. 2 Ho: 01 02 = H: 02 02 Ho: 1 O > 2 2 02. 2502 H: 1 2 Ho: 002 H: 01 > 02 2 2+02 Ho: 12 Ha: 01 02 Find the value of the test statistic. (Round your answer to two decimal places.) Find the p-value. (Round your answer to four decimal places.) p-value= State your conclusion. Do not reject Ho. We cannot conclude that the process variances are significantly different. Do not reject Ho. We can conclude that the process variances are significantly different. Reject Ho We cannot conclude that the process variances are significantly different.
