You may use Minitab or other software for any calculations. However, you must show your

manual calculations when asked. You may paste your output onto your assignment to show your use of Minitab; however, this output does not replace any of the steps outlined below. This means that answers that are exclusively computer output may receive only one mark.

If you are performing a hypothesis test, make sure you state the hypotheses, the level of significance, the rejection region, the test statistic (and p-value, if requested), your decision (whether to reject or not to reject the null hypothesis), and a conclusion that answers the question posed or interprets the decision taken. These steps must be completed in addition to any computer output.

The data in the Minitab data files can be found in the file Assign1Data.xlsx.
