A) p (7)
B) p (7) + p (8)
C) p (0) + p (1) + p (7) + p (8)
D) p (0) + p (8)

The nondirectional alternative hypothesis is that the probability of observing 7 pluses out of 8 events is not equal to 0.5. The probability of observing 7 pluses out of 8 events is p(7) = 0.21875. The probability of observing 8 pluses out of 8 events is p(8) = 0.0625. The probability of observing 0 pluses out of 8 events is p(0) = 0.0625. The probability of observing 1 plus out of 8 events is p(1) = 0.1875. The sum of these probabilities is p(0) + p(1) + p(7) + p(8) = 0.53125.
