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...
