Assembly Line. Three assembly lines are used to produce a certain component for a computer. To examine the production rate of the assembly lines, a random sample of six hourly periods is chosen for each assembly line, and the number of components produced during these periods for each line is recorded. These data are available in a file named ASSEMBL9 on the CD. In the MINITAB file, the number of components produced will be in one column. A second column will indicate the production line (coded as 1, 2, or 3). In the Excel spreadsheet, the production numbers will be in a separate column for each production line.
Is there a difference in the average production rates for the three assembly lines? Use a 5% level of significance in answering this question. State any hypotheses to be tested, the decision rule, the test statistic, and your decision.
