Let x be the number of cars that a randomly selected auto mechanic repairs on a given day. The following table lists the probability distribution of x.
Find the mean and standard deviation of x. Give a brief interpretation of the value of the mean.
Answer to relevant QuestionsEach of the following tables lists certain values of x and their probabilities. Determine whether or not each one satisfies the two conditions required for a valid probability distribution and explain why. a. x ...At the Bank of California, past data show that 8% of all credit card holders default at some time in their lives. On one recent day, this bank issued 12 credit cards to new customers. Find the probability that of these 12 ...Briefly explain when a hypergeometric probability distribution is used. Give one example of a hypergeometric probability distribution. For the standard normal distribution, find the area within one standard deviation of the mean—that is, the area between μ − σ and μ + σ For the standard normal distribution, what is the area within two standard deviations of the mean?
