You may need to use the appropriate technology to answer this question. 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 the process variance.

Use a 0.05 level of significance. (Hint: Organize the data in two rows, one for each Machine before running the analysis). State the null and alternative hypotheses. - 2 202 - 2# 02, O 1: 2 -02 H.: 1 2 O 2=07 Ho' $ 2 + 02 H: 1 2 0 1 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. O Do not reject Ho. We cannot conclude that the process variances are significantly different. O Reject Ho. We cannot conclude that the process variances are significantly different. O Do not reject Ho. We can conclude that the process variances are significantly different. O Reject Ho. We can conclude that the process variances are significantly different. Which machine, if either, provides the greater opportunity for quality improvements? Machine 1 offers the best opportunity for process quality improvements. O Machine 2 offers the best opportunity for process quality improvements. Neither machine offers an opportunity for process quality improvements
