Question Help

A sociologist randomly selects single adults for different groups ofthree, and the random variable x is the number in the group who say that the most fun way to flirt is in person. Determine whether a probability distribution is given. If a probability distribution isgiven, find its mean and standard deviation. If a probability distribution is notgiven, identify the requirements that are not satisfied.

P(x)

0.092

0.343

0.391

0.174

Does the table show a probabilitydistribution? Select all that apply.

Yes, the table shows a probability distribution.

No, the random variablex's number values are not associated with probabilities.

No, not every probability is between 0 and 1 inclusive.

No, the sum of all the probabilities is not equal to 1.

No, the random variable x is categorical instead of numerical.

Find the mean of the random variable x. Select the correct choice belowand, ifnecessary, fill in the answer box to complete your choice.
