Let Z be a standard normal random variable. Use the calculator provided, or this table, to determine the value of c. P(−c≤Z≤c)=0.9476 Carry your intermediate computations to at least four decimal places. Round your answer to two decimal places.

Find the variance of x or the number of cups of coffee. (Do not round intermediate steps but round your final answer to 4 decimal places)

Groups of adults are randomly selected and arranged in groups of three. The random variable x is the number in the group who say that they would feel comfortable in a self-driving vehicle. 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. OA. H= O B. The table does not show a probability distribution. X P(x) 0 0.368 0.435 0.171 0.026 adult(s) (Round to one decimal place as needed.) 1 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 sum of all the probabilities is not equal to 1. D. No, the random variable x's number values are not associated with probabilities. E. No, the random variable x is categorical instead of numerical. Find the mean of the random variable x.…

Consider a game of rolling a single die, with the outcome as the random variable X. A player gains $10 if the outcome is {1, 2, 3} and a player loses $5 if the outcome is (4, 5, or 6}. It does not cost anything to play the game. Calculate o. Round to 2 decimal places.
