a brand of candy-coated chocolates come in three colors: red, blue, and yellow (the three primary colors). according to the manufacturer, the true percentages of red, blue, and yellow candies are 40%, 35%, and 25%, respectively. in a random sample of candies, there were 187 red, 140 blue, and 98 yellow candies. at the 2.5% level of significance, we will test whether the distribution of observed frequencies provides evidence that the true distribution of red, blue, and yellow candies is different from 40%, 35%, and 25%, respectively. assume all conditions for a goodness-of-fit test are met. answer each of the following. the test statistic is (enter your answer using two decimal places. ) the test statistic has a chi-square distribution with degrees of freedom (df) = the critical value for a right-tail area of 0.025 is
