Question
I just need x2 & p-value
= You are conducting a multinomial hypothesis test (a 0.05) for the claim that all 5 categories are equally likely to be selected. Complete the table. Note: Expected frequency is E = np. Category A B C D E Observed Frequency 11 21 15 18 15 Expected Frequency 16 16 16 16 16 Report all answers accurate to three decimal places. But retain unrounded numbers for future calculations. What is the chi-square test-statistic for this data? (Report answer accurate to three decimal places, and remember to use the unrounded Pearson residuals in your calculations.) x² = 12.432 X What are the degrees of freedom for this test? d.f. = 4 What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = 0.0673 X
