Test: Final Exam Question 4 of 20 This test: 20 point(s) possible Submit test This question: 1 point(s) possible Households are randomly selected and partitioned into groups of four. For those groups, the random variable x is the number of households with a printer. Determine whether a probability distribution is given. If a probability X P(X) distribution is given, find its mean and standard deviation. If a probability distribution is not given, identify the requirements that are not satisfied. 0 0 022 0.145 20 345 0 357 0.131 Does the table show a probability distribution? Select all that apply A. Yes, the table shows a probability distribution. [B. No, the numerical values of the random variable x are not associated with probabilities C. No, not every probability is between 0 and 1 inclusive. [)D. No, the random variable x is categorical instead of numerical. ")E. No, the sum of all the probabilities is not equal to 1 Find the mean of the random variable x. Select the correct choice below and, if necessary, fill in the answer box to complete your choice O A u= household(s) (Round to one decimal place as needed.) O B. The table does not show a probability distribution. Find the standard deviation of the random variable x. Select the correct choice ry. fill in the answer box to complete your choice OA = household(s) (Round to one decimal place as needed.) O B. The table does not show a probability distribution
