The test statistic is 5.840
(Round to three decimal places as needed.)
The critical value is 6.251
(Round to three decimal places as needed.)
State the conclusion.
Reject Ho. There is not sufficient evidence to warrant rejection of the 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.
