Question

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 1,179. 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 = 18.368. Use a .05 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?

Explanation / Answer

Given a=0.05, the critical value= chisquare(with a=0.025, df=n-1=9) = 2.7 chisquare(with a=0.975, df=n-1=9) = 19.02 (check chisquare table) Since X^2=18.368
