Conduct the hypothesis test and provide the test statistic and the critical​ value, and state the conclusion.   A person purchased a slot machine and tested it by playing it 1,139 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 χ2=15.992. Use a 0.10 significance level to test the claim that the actual outcomes agree with the expected frequencies. Does the slot machine appear to be functioning as​ expected?   a. The test statistic is ���(Type an integer or a decimal. Do not​ round.)   b. The critical value is ​(Round to three decimal places as​ needed.)
