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

0.10 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?

What is the test statistic?

what is the p-value?

Cents portion of check	0-24	25-49	50-74	75-99
Number	31	23	18	28
