Test at 0.05 level of significance whether there is a significant difference between the different degrees. An engineer wants to determine if there is a relationship between the power setting and the etch rate power settings (160W, 180W, 200W and 220W). The engineer tested five wafers a plasma etching process. She is using four different at each power level. The data from the experiment are shown below.
