I wrote this as a initial report and the feedback from the instructor is

You have collected good data but your analysis and the hypothesis tested need some work. What is the value of testing data collected from different shifts for interaction ? The hypothesis comparing the shift seems correct, but your conclusion does not make sense : In this case we will fail to reject the H01. This is because H01: Shift 2

Can someone fix the errors according to this feedback?



"In this case we will fail to reject the H01. This is because H01: Shift 2

Milestone 2 Initial Report QSO530 Q3768 Executive Summary The purpose of this report is to analysis the leak test machine downtime. The test will be for two different shifts and one leak tester for comparison. Staff level management requested the study to ensure the processes were being followed according to company policy. The standard for escalating downtime issues on any assembly line is a threshold of two hours. This standard is for cumulative downtime or a single event. This will help to determine if retraining the operators in proper escalation procedures will be necessary or if the equipment needs to be adjusted. The data will be collected for 22 days covering a normal month of daily production time. The report will show the F-statistic from ANOVA to determine if there is any interaction between Factor A (1 Leak Test Downtime) and Factor B (Total Leak Test Downtime) (Groebner, 2014). The p -value calculation will aid in determining if there are differences in the means between Factor A and Factor B at a significance level of 0.05. The F-test computation from ANOVA table gives a decision rule according to the null and alternative hypothesis that is tested. Both null hypotheses that will be tested in this report are H 01 and H 02 . With a conclusion to reject or fail to reject at 95% confidence level. The report is broken down in the following areas; a description of the report, the sampling and size of the sampling, the data that was collected, the statistical methods, and last will be the conclusion. Description of the Report The company has a standard operations procedure to cover excessive downtime during a shift. The policy is to escalate downtime issues if total downtime during a shift, for the same reason, reaches two hours. This analysis was conducted to see if there is indeed excessive downtime and if the process is being followed. The report is the compilation of the data 2
