Consider the observed frequency distribution for the set of random variables on the right. a. Perform a chi-square test using a = 0.05 to determine if the observed frequencies follow the binomial probability distribution when p = 0.50 and n= 4. b. Determine the p-value and interpret its meaning. Random Variable, x Frequency, f. 31 93 153 102 21 Total 400 ... O A. Ho: The distribution of the random variable is not binomial with n = 4 and p = 0.50 Hy: The distribution of the random variable is binomial with n= 4 and p = 0.50. OB. Ho: The mean number of the random variable is equal to 0. H: The mean number of the random variable is less than 0. OC. Ho: The distribution of the random variable is binomial with n = 4 and p = 0.50. H: The distribution of the random variable is not binomial with n = 4 and p = 0.50. O D. Ho: The mean number of the random variable is equal to 0. H: The mean number of the random variable is not equal to 0. The chi-square test statistic is x2 = (Round to two decimal places as needed.) The chi-square critical value is xa =D (Round to three decimal places as needed.) Determine the proper conclusion. Choose the correct answer below. O A. Do not reject the null hypothesis. There is not enough evidence to conclude that the random variable does not follow a binomial probability distribution with n = 4 and p=0.50. OB. Reject the null hypothesis. There is not enough evidence to conclude that the random variable does not follow a binomial probability distribution with n = 4 and p = 0.50. OC. Reject the null hypothesis. There is enough evidence to conclude that the random variable does not follow a binomial probability distribution with n= 4 and p= 0.50. OD. Do not reject the null hypothesis. There is enough evidence to conclude that the random variable does not follow a binomial probability distribution with n = 4 and p=0.50. b. p-value = 1 (Round to three decimal places as needed.) State the appropriate conclusion. the null hypothesis because the p-value is a. There is evidence to conclude that the observed frequency distribution does not follow a binomial probability distribution.
