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 0.094 most fun way to flirt is in person. Determine whether a probability 1 0.341 distribution is given. If a probability distribution is given, find its mean and 2 0.398 standard deviation. If a probability distribution is not given, identify the requirements that are not satisfied. 3 0.167 Does the table show a probability distribution? Select all that apply. O A. Yes, the table shows a probability distribution. B. No, the random variable x's number values are not associated with probabilities. OC. No, the sum of all the probabilities is not equal to 1. O D. No, the random variable x is categorical instead of numerical. O 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. = 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. g= adult(s) (Round to one decimal place as needed.) O B. The table does not show a probability distribution
