Households Are Randomly Selected And Partitioned Into Groups Of Four For Those Groups The Random Variable X Is The Num 2 (7.52 KiB) Viewed 30 times
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 distribution is given, find its mean and standard deviation. If a probability distribution is not given, identify the requirements that are not satisfied. 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 random variable x is categorical instead of numerical. D. No, not every probability is between 0 and 1 inclusive. E. No, the sum of all the probabilities is not equal to 1. 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. μ= household(s) (Round to one decimal place as needed.) OB. The table does not show a probability distribution. X 0 0.028 0.148 0.334 0.352 0.138 1-1/32/4 P(x) = pleabil
