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 mean and standard deviation. If a probability distribution is not given, identify the requirements that are not satisfied. X P (X) 0 0.028 1 0.145 2 0.335 3 0.356 4 0.136 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, the sum of all the probabilities is not equal to 1. D. No, the random variable x is categorical instead of numerical. E. No, not every probability is between 0 and 1 inclusive. 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. OA H= household(B) (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, O A = household(s) (Round to one decimal place as needed.) B. The table does not show a probability distribution. Next Help me solve this View an example Get more help
