What is the critical value? What is the p-value? And state the conclusion. Homework: Module 7 Homework Score: 0 of 1 pt 11.2.7-T Save 3 of 13 (2 complete) Hw Score: 15.38%, 2 of 13 pts Question Help Conduct the hypothesis test and provide the test statistic, critical value and P-value, and state the conclusion A person purchased a slot machine and tested it by playing it 1,235 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 o2 -20.813. Use a 0.025 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? The test statistic is 20.813·(Type an integer or a decimal.) The critical value is (Round to three decimal places as needed.)

Explanation / Answer

Degrees of freedom = n - 1 = 10 - 1 = 9

So for 9 degrees of freedom and 0.025 significance level,

Critical value = 19.023

p - value = P(X2 > 20.813) = 0.0135

Conclusion: Since p - value is less than the significance level, we reject the null hypothesis. Hence,

We have enough evidence to reject the claim that the actual outcome agree with expected frequencies.
