hypothesis test suggested by Quality Associates follows: H0: μ=12 Ha: μ≠ 12 Corrective action will be taken when H0 is rejected. Samples collected during the first day of operation of the new statistical process-control procedure are in the file Quality.xls. The URL to this dataset is A. Conduct a hypothesis test for each sample at the .01 level of significance and determine what action, if any should be taken, Answer H0: μ=12 Ha: μ≠ 12 Test Statistic used is Z test Decision

Some of the tools that may be used include correlation and regression, or derivatives such as the t-test, analysis of variance, and contingency table (crosstabulation) analysis. The type of analysis chosen depends on the research design, characteristics of the
