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 distribution is given, find its x P(x) mean and standard deviation. If a probability distribution is not given, identify the requirements that are not satisfied. 0.021 0.143 0.346 O 0.357 0.133 O Does the table show a probability distribution? Select all that apply. O O)A. Yes, the table shows a probability distribution. OB. No. the random variable x is categorical instead of numerical. O C. No. the sum of all the probabilities is not equal to 1. D. No. not every probability is between 0 and 1 inclusive. O E. No. the numerical values of the random variable x are not associated with probabilities. O 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 O A. = household(s) (Round to one decimal place as needed.) O B. The table does not show a probability distribution. O 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. O A. 6= household(s) O (Round to one decimal place as needed.) O B.
