A person purchased a slot machine and tested it by playing it 1,137 times. There are 10 different categories of outcomes, including no win, win jackpot, win with three bells, and so on. When testing the claim that the observed outcomes agree with the expected frequencies, the author obtained a test statistic of x2 = 11.517. Use a .10 significance level to test the claim that the actual outcomes agree with the expected frequencies.What is the P-Value?
