Exercise 12-1 Algo Consider a multinomial experiment with n = 260 and k = 4. The null hypothesis to be tested is He : P1 = p2 = P3 = p4 = 0.25. The 33 Mints observed frequencies resulting from the experiment are: (You may find it useful to reference the appropriate table: chi-square table or F table) eBook Category 1 2 3 Hint Frequency 73 44 75 68 Print a. Choose the appropriate alternative hypothesis. References O All population proportions differ from 0.25. O Not all population proportions are equal to 0.25. b-1. Calculate the value of the test statistic. (Round intermediate calculations to at least 4 decimal places and final answer to 3 decimal places.) Test statistic
