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 P(x) 21 distribution is given, nd its mean and standard deviation. If a probability distribution is not given, identify the requirements that are not satised. 0.024 0.146 0.344 0.352 0.134 Does the table show a probability distribution? Select all that apply. 1 A. Yes, the table shows a probability distribution. B. No, not every probability is between 0 and 1 inclusive. _ C. No, the random variable x is categorical instead of numerical. _ D. No, the sum of all the probabilities is not equal to 1. I: 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, ll in the answer box to complete your choice. (9 A- p.= 2.4 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 below and, if necessary, ll in the answer box to complete your choice. A- a = 1.0 household(s) (Round to one decimal place as needed.) O B. The table does not show a probability distribution
