erform the indicated goodness-of-fit test. In studying the responses to a multiple-choice test question, the following sample data were obtained. At the 0.05 significance level, test the claim that the responses occur with the same frequency. There are a total of 80 responses. Response A B C D E Frequency 12 15 16 18 19 What is the expected value for each frequency? Use this formula to calculate the Chi-squared statistic. (x^2=Sum[(observed-expected)^2/expected] Based on your test statistic, what would be the p value or probability this distribution comes from a uniform distribution (all the same frequency)? Use a significance level of 0.05 to test the claim, do you think the distribution of answers to this multiple choice test fit a uniform model?
