Extracted text: Past records indicate that the probability of online retail orders that turn out to be fraudulent is 0.07. Suppose that, on a given day, 18 online retail orders are placed. Assume that the number of online retail orders that turn out to be fraudulent is distributed as a binomial random variable. Complete parts (a) through (d) below. a. What are the mean and standard deviation of the number of online retail orders that turn out to be fraudulent? The mean number of online retail orders that turn out to be fraudulent is (Type an integer or a decimal. Round to four decimal places as needed,) Instructor tip The standard deviation of the number of fraudulent retail orders is. (Type an integer or a decimal. Round to three decimal places as needed.) Use BINOM.DIST function in Excel to find binomial probabilities. Use the formulas for the mean and the SD. See my Excel tutorials for b. What is the probability that zero online retail orders will turn out to be fraudulent? more information. (Type an integer or a decimal. Round to four decimal places as needed.) c. What is the probability that one online retail order will turn out to be fraudulent? (Type an integer or a decimal. Round to four decimal places as needed.) d.
