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? Cents portion of check ​0-24, ​25-49, ​50-74, ​75-99 Number 61, 18. 9, 12 Click here to view the chi-square distribution table. The test statistic is nothing. ​(Round to three decimal places as​ needed.)

Answer 1

For critical value chisq table can be used, I have used Excel

Conclusion= since , Test stats is greater than critical value so, Reject Ho and we can conclude that the four categories are not equally likely
