A sociologist randomly selects single adults for different groups of three, X P(x) and the random variable x is the number in the group who say that the 0 0.093 most fun way to flirt is in person. Determine whether a probability 1 distribution is given. If a probability distribution is given, find its mean and 0.329 standard deviation. If a probability distribution is not given, identify the 2 0.404 requirements that are not satisfied. 3 0.174 Does the table show a probability distribution? Select all that apply. A. Yes, the table shows a probability distribution. B. No, the random variable x's number values are not associated with probabilities. C. No, the sum of all the probabilities is not equal to 1. OD. No, not every probability is between 0 and 1 inclusive. O E. No, the random variable x is categorical instead of numerical. 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. U= adult(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. 6= adult(s) (Round to one decimal place as needed.) O B. The table does not show a probability distribution
