Using data below and a 0.05 significance level, test the claim that the responses occur with percentages of 15%, 20%, 25%, 25%, and 15% respectively.
The answer is H0: The responses occur according to the stated percentages.
H1: The responses do not occur according to the stated percentages.
Test statistic: X2 = 5.146. Critical value: X2 = 9.488. Fail to reject the null hypothesis. There is not sufficient evidence to warrant rejection of the claim that the responses occur according to the stated percentages.
