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 0.05 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 35 19 27 19   Hypothesis test? Test Statistic?  Critical Value? Conclusion?
