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 h 0: p = 0.25 versus h a: p > 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? group of answer choices p‐value = 0.009 p‐value = 0.991 p‐value = 0.018 p‐value = 0.05

A. plot the data for the functions f(x) and g(x) on a grid and connect the points. x -2 -1 0 1 2 f(x) 1/9 1/3 1 3 9 x -2 -1 0 1 2 g(x) -4 -2 0 2 4 b. which function could be described as exponential and which as linear? explain. c. if the functions continue with the same pattern, will the function values ever be equal? if so, give estimates for the value of x that will make the function values equals. if not, explain why the function values will never be equal.
