For this part ot the exercise, we want to see the sample size eitect ot manipulating alpha while holding other factors constant. Use the data achieved in the pilot study, and determine the sample size needed when alpha takes the following values. Start by calculating delta (the difference in means), and then go to 1'5 software with the appropriate numbers to enter for alpha (starting with 0.01 as listed in the table below) and also for power, delta, sigma, and m. You will keep everything constant in subsequent iterations of the program, but changing alpha each time. Enter the computed samples sizes below. What trend do you see? Alpha .01 ' .02 ' .05 ' 0.10 - Trend
