Question: 1. Suppose a researcher chooses to use a = .01 rather than .05. What effect does this have on the probability of Type I and Type II errors?
2. The following table has blanks for you to fill in. Look up critical values in Table D, decide if H0 should be rejected or retained, and give the probability figure that characterizes your confidence in that decision. Check the answer for each line when you complete it. (Be careful not to peek at the next answer.) I designed this table so that some common misconceptions will be revealed-just in case you acquired one.
