The table below lists the frequency of wins for different post positions in a horse race. A post position of 1 is closest to the inside rail, so that horse has the shortest distance to run. (Because the number of horses varies from year to year, only the first 10 post positions are included.) Use a 0.05 significance level to test the claim that the likelihood of winning is the same for the different post positions. Based on the result, should bettors consider the post position of a horse race? Post Position 1 2 3 4 5 6 7 8 9 10 Wins 1818 1515 1111 1515 1313 77 99 1212 55 1111 Determine the null and alternative hypotheses. Upper H 0H0: Wins occur with equal frequency in the different post positions. Upper H 1H1: At least one post position has a different frequency of wins than the others. Calculate the test statistic, chi squaredχ2. chi squaredχ2equals= (Round to three decimal places as needed.) Calculate p value P value=
