Birthdays of hockey players: In Malcolm Gladwell’s book "Outliers" he shares the work of Canadian psychologist Roger Barnsley, who noticed that a disproportionately high percentage of elite ice-hockey players have birthdays between January and March. A group of statistics students would like to test if this is true for the Los Angeles Kings 2010-2015 rosters (22 out of 57). After debating whether this set of hockey players can be viewed as a random sample of hockey players, they decide to run a hypothesis test anyway to practice finding the P‐value. They test the hypotheses LaTeX: H_0H 0: LaTeX: p=0.25p = 0.25 versus LaTeX: H_aH a: LaTeX: p>0.25p > 0.25. They use a significance level of 0.05. Their calculated test statistic is 2.37. Using the applet (at the top of this Checkpoint), what is the P‐value?
a. P‐value = 0.009
b. P‐value = 0.991
c. P‐value = 0.018
d. P‐value = 0.05
