In a survey, cell phone users were asked which ear they use to hear their cell phone, and the table is based on their responses. 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 sum of all the probabilities is not equal to 1. E. No, the random variable x is categorical instead of numerical. Left Right No preference P(x) D 0.636 0.3042 0.0598
