Problem 12-05 To generate leads for new business, Gustin Investment Services offers free financial planning seminars at major hotels in Southwest Florida. Gustin conducts seminars for groups of 25 individuals. Each seminar costs Gustin $3500, and the average first-year commission for each new account opened is $5200. Gustin estimates that for each individual attending the seminar, there is a 0.01 probability that he/she will open a new account. a. Determine the equation for computing Gustin's profit per seminar, given values of the relevant parameters. Round your answers to the nearest dollar. Profit = (New Accounts Opened $ 5,200 ) - $ 3,500 b. What type of random variable is the number of new accounts opened? (Hint: Review Appendix 12.1 for descriptions of various types of probability distributions.) random variable with 25 trials and 0.01 The number of new accounts opened is a binomial c. Assume that the number of new accounts you get randomly is: Simulation Trial New Accounts 1 0 2 0 3 1 4 0 5 0 6 0 7 0 8 0 probability of a success on a single trial. 0 6 0 202 2 10 12 0 1 2 3 4 5 11 13 14 15 0 62222222 16 1 17 0 18 0 19 0 20 0 21 0 0 23 1 24 0 25 2 Construct a spreadsheet simulation model to analyze the profitability of Gustin's seminars. Round the answer for the expected profit to the nearest dollar. Round the answer for the probability of a loss to 2 decimal places. Enter minus sign for negative values. The expected profit from a seminar is $ and there is a 0.72 probability of a loss. Would you recommend that Gustin continue running the seminars? Gustin should consider discontinuing the seminars in their current format. d. How large of an audience does Gustin need before a seminar's expected profit is greater than zero? Use Trial-and-error method to answer the question. Round your answer to the nearest whole number. attendees
