Households are randomly selected and partitioned into groups of four. For those groups, the P(x) random variable x is the number of households with a printer. Determine whether a probability 0.028 distribution is given. If a probability distribution is given, find its mean and standard deviation. If a 0.144 probability distribution is not given, identify the requirements that are not satisfied. 0343 0.351 0.134 Does the table show a probability distribution? Select all that apply. [II A. Yes, the table shows a probability distribution. [1 B. No, the sum of all the probabilities is not equal to 1. [:l C. No, the numerical values of the random variable x are not associated with probabilities. [:l D. No, the random variable x is categorical instead of numerical. [j 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, ll in the answer box to complete your choice. LI? A- 1.1 = household(s) (Round to one decimal place as needed.) If? 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. '31- A- o = 0.1 household(s) (Round to one decimal place as needed.) {:2- B. The table does not show a probability distribution
