You are conducting a multinomial Goodness of Fit hypothesis test for the claim that the 4 categories occur with the following frequencies: Ho: pA = 0.3; pB = 0.2; pC = 0.2; pD = 0.3 Complete the table. Report all answers accurate to three decimal places. Category Observed Frequency Expected Frequency A 29 29 B 22 22 C 23 23 D 38 38 What is the chi-square test-statistic for this data? χ2 = What is the P-Value? P-Value = For significance level alpha 0.01, what would be the conclusion of this hypothesis test? Fail to reject the Null Hypothesis Reject the Null Hypothesis

Step 1
First, we need to find the total number of observations. We can do this by adding the observed frequencies for each category: Total observations = 29 (A) + 22 (B) + 23 (C) + 38 (D) = 112 Show more…
