The graph below shows six different curves labeled A€“F. Each curve shows the relationship between the p-value (y-axis) and the distance pˆ ˆ’ Ï€ (x-axis) for testing the null hypothesis Ï€ = 0.50.
Match each curve A€“F with one of the descriptions:
Sample size is n = 25, alternative hypothesis is right sided: Ï€ > ½.
Sample size is n = 225, alternative hypothesis is right sided: Ï€ > ½.
Sample size is n = 25, alternative hypothesis is left sided: Ï€ < ½.
Sample size is n = 225, alternative hypothesis is left sided: Ï€ < ½.
Sample size is n = 25, alternative hypothesis is two sided: Ï€ ‰  ½.
Sample size is n = 225, alternative hypothesis is two sided: Ï€ ‰  ½.

Comment: This is not an easy exercise, but don€™t let the surface mess of the picture put you off . The purpose of the exercise is to challenge you to think hard about very important issues in a new way and at the same time to challenge you to become more skillful at connecting graphs with ideas. We hope you won€™t give up and that you€™ll feel that what you learn from the time you spend is worth it. Give it a shot, see how far you can get, and if you get stuck, skip to the five exercises that come after the graphs, do those, and then come back to this one.
