X P(x) 2 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 0.028 distribution is given, find its mean and standard deviation. If a probability distribution is not given, identify the requirements that are not satisfied. 0.146 2 0.336 3 0.358 4 0.132 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. . 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. 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 below and, if necessary, fill in the answer box to complete your choice. O A a= household(s) (Round to one decimal place as needed.) O B. The table does not show a probability distribution. Tutoring Help me solve this Get more help
