Compute the mean number of accidents per day.b. Compute the standard deviation.5.10 If n = 5 and = 0.40, what is the probability thata. X = 4?b. X ? 3?c. X < 2?d. X > 1?5.15 When a customer places an order with Rudys On-Line Office Supplies, a computerized accounting information system (AIS) automatically checks to see if the customer has exceeded his or her credit limit. Past records indicate that the probability of customers exceeding their credit limit is 0.05. Suppose that, on a given day, 20 customers place orders. Assume that the number of customers that the AIS detects as having exceeded their credit limit is distributed as a binomial random variable. a. What are the mean and standard deviation of the number of customers exceeding their credit limits?
b. What is the probability that zero customers will exceed their limits?c. What is the probability that one customer will exceed his or her limit?5.21 Assume that the number of network errors experienced in a day on a local area network (LAN) is distributed as a Poisson random variable. The mean number of networkerrors experienced in a day is 2.4. What is the probability that in any given daya. zero network errors will occur?b. exactly one network error will occur?c. two or more network errors will occur?d. fewer than three network errors will occur? 5.22 The quality control manager of Marilyns Cookies is inspecting a batch of chocolate-chipcookies that has just been baked. If the production process is incontrol, the mean number of chip parts per cookie is 6.0. Whatis the probability that in any particular cookie being inspecteda. fewer than five chip parts will be found?b. exactly five chip parts will be found?c. five or more chip parts will be found?d. either four or five chip parts will be found?Assignment Chapter 5 Problem SetDetails:Complete problems in the textbook.Submit one Excel file.
