. We would like to conduct a hypothesis test at the 10% level of significance to determine whether the true mean score of all players in a bowling league differs from 150. The mean and standard deviation of the scores of 12 randomly selected players are calculated to be 170 and 16, respectively. Scores of all players in the league are known to follow a normal distribution. The P-value of the appropriate test of significance is
