Conduct the hypothesis test and provide the test statistic, critical value and P-value, and state the conclusion.
A person randomly selected
100
checks and recorded the cents portions of those checks. The table below lists those cents portions categorized according to the indicated values. Use a
0.10
significance level to test the claim that the four categories are equally likely. The person expected that many checks for whole dollar amounts would result in a disproportionately high frequency for the first category, but do the results support that expectation?

slot machine and tested it by playing it 1,156 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 chi squared equals18.233. Use a 0.05
