Question
Transcribed Image Text:College students are randomly selected and arranged in groups of three. The random variable x is the number in the group who say that they take one or more online courses. 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, not every probability is between 0 and 1 inclusive.
C. No, the numerical values of the random variable x are not associated with probabilities.
☐D. No, the random variable x is categorical instead of numerical.
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.
