Unformatted text preview: Step 2a (Again), Draw the distribution of the test statistic under Ho Step 2b Locate and label the value of the observed statistic on 2a Step 2c Shade a tail area relative to the value in 2b Step 2d Label the shaded area in 2c in terms of p (most often, it will be labeled p, p/2 or 1-p). Step 3 Using the Step 2 picture, find p. Complete the above steps to solve: Example 1: Find the p value if a Global F obs = 3.5 given F obs ~F 5,8 under Ho Example 2: Find the p value if t obs =-2 given t obs ~t 14 under Ho for a rejection region for t obs that is a) very negative; b) very negative or very positive; and c) very positive. (there are 3 separate problems, 2a, 2b and 2c that need solutions)....
