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) 2 0 distribution is given, find its mean and standard deviation. If a probability distribution is not given, identify the requirements that are not satisfied. 0.023 1 0.148 2 0.344 3 0.352 0.133 Does the table show a probability distribution? Select all that apply. A. Yes, the table shows a probability distribution. [B. No, the random variable x is categorical instead of numerical. C. No, not every probability is between 0 and 1 inclusive. D. No, the sum of all the probabilities is not equal to 1. E. No, the numerical values of the random variable x are not associated with probabilities. 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. (= household(s) (Round to one decimal place as needed.) B. The table does not show a probability distribution. Find the standard deviation of the random variable x. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA o= household(s) (Round to one decimal place as needed. B. The table does not show a probability distribution
