Question
Conduct the hypothesis test and provide the test statistic and the critical 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 0.025 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?
