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?
| Cents Portion of check | 0-24 | 25-49 | 50-74 | 75-99 |
| Number | 31 | 20 | 21 | 28 |
A. Find Test Statistic
B. Find Critical Value
C. State the conclusion
