B.
Because this probability is notsmall, reject the null hypothesis. There is sufficient evidence to conclude that thedart-picking strategy resulted in a majority of winners.
C.
Because this probability issmall, reject the null hypothesis. There is sufficient evidence to conclude that thedart-picking strategy resulted in a majority of winners.
