Try to relate the shape of the curve to the alternate hypothesis.
a. Suppose Buzz really wants to earn his fish and tries to guess right. Your alternative hypothesis is that π > 0.50. Th e better Buzz does, the _____ (smaller, larger) the p-value. The graph should be _________ (increasing, decreasing, up down). The graphs that match this alternative are _______.
b. Suppose you are studying sadism in dolphins and your research hypothesis is that Buzz is able to guess right but he wants only to deprive Doris of her fish. Your alternative hypothesis is that π < 0.50. Th e better Buzz does, the ______ (smaller, larger) the p-value. The graph should be _________ (increasing, decreasing, up-down).
The graphs that match this alternative are ______.
c. You are unsure about whether Buzz is fi sh-greedy or sadistic. Your more objective alternative hypothesis is that Ï€ ‰  0.50. The graphs that match this alternative are _______ (increasing, decreasing, up-down). Th eir letters are ________.

d. Complete the following summary table. For €œStrongest evidence,€ choose from among pÌ‚  = 0, pÌ‚ = 1, and pÌ‚ = 0 or 1. For €œShape of curve,€ choose from among increasing, decreasing, and up-down.
