A sociologist randomly selects single adults for different groups of three, P(x) Ch and the random variable x is the number in the group who say that the 0.086 most fun way to irt is in person. Determine whether a probability 0 333 distribution is given. If a probability distribution is given, nd its mean and ' standard deviation. If a probability distribution is not given, identify the 0423 requirements that are not satised. 0.158 Does the table show a probability distribution? Select all that apply. E] A. Yes, the table shows a probability distribution. E] B. No, not every probability is between 0 and 1 inclusive. E] C. No, the random variable x's number values are not associated with probabilities. E] D. No, the sum of all the probabilities is not equal to 1. E] 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, ll in the answer box to complete your choice. O A- ll: 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, ll in the answer box to complete your choice. O A- 5 = adult(s) (Round to one decimal place as needed.) O B. The table does not show a probability distribution
