Consider a multinomial experiment with n = 400 and k = 3. The null hypothesis is H0: p1 = 0.60, p2 = 0.25, and p3 = 0.15. The observed frequencies resulting from the experiment are: (You may find it useful to reference the appropriate table: chi-square table or F table)

Consider a multinomial experiment with n = 400 and k = 3. The null hypothesis is No: p1 = 0.60, p2 = 0.25, and pg = 0.15.

Choose the appropriate alternative hypothesis. O All population proportions differ from their hypothesized values. O At least one of the population proportions differs from its hypothesized value. 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
