Transcribed Image Text:Conduct the hypothesis test and provide the test statistic and the cntical value, and state the conclusion.
Aperson 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?

The test statistic is
(Round to three decimal places as needed.)
The critical value is
(Round to three decimal places as needed.)
State the conclusion,
Reject
Ho. There is not sufficient evidence to warrant rejection ofthe claim that the four categories are
equally likely. The results do not appear to support the expectation that the frequency for the first category is
disproportionately high.
