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 $3,700, and the average first-year commission for each new account opened is
$5,200. Gustin estimates that for each individual attending the seminar, there is a 0.01 probability that individual will open a new account.
(a) Determine the equation for computing Gustin's profit per seminar, given values of the relevant parameters.
Profit = (3,700 x 5,200) - New Accounts Opened
Profit = 5,200 - (New Accounts Opened x 3,700)
Profit = (New Accounts Opened x 3,700) - 5,200
Profit = New Accounts Opened - (5,200 × 3,700)
Profit = (New Accounts Opened x 5,200) - 3,700
(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.
continuous
integer uniform
normal
discrete uniform…
Strassel Investors buys real estate, develops it, and resells it for a profit. A new property is available, and Bud Strassel, the president and owner of Strassel Investors, believes if he purchases and develops this property, it can then be sold for $158,000. The current property owner has asked for bids
and stated that the property will be sold for the highest bid in excess of $100,000. Two competitors will be submitting bids for the property. Strassel does not know what the competitors will bid, but he assumes for planning purposes that the amount bid by each competitor will be uniformly distributed
between $100,000 and $148,000.
(a) What is the estimate of the probability Strassel will be able to obtain the property using a bid of $128,000? (Use at least 5,000 trials. Round your answer three decimal places.)
(b) How much does Strassel need to bid to be assured of obtaining the property?
$128,000
$138,000
$148,000
(c) Use the simulation model to compute the profit for each trial of…
Grear Tire Company has produced a new tire with an estimated mean lifetime mileage of 34,500 miles. Management also believes that the standard deviation is 4,500 miles and that tire mileage is normally distributed. To promote the new tire, Grear has offered to refund a portion of the purchase price
if the tire fails to reach 30,000 miles before the tire needs to be replaced. Specifically, for tires with a lifetime below 30,000 miles, Grear will refund a customer $1 per 100 miles short of 30,000. Construct a simulation model to answer the following questions. (Use at least 1,000 trials.)
(a) For each tire sold, what is the average cost of the promotion (in $)? (Round your answer to two decimal places.)
(b) What is the probability that Grear will refund more than $25 for a tire? (Round your answer to three decimal places.)

The following table contains information on the number of RSVP guests for the 145 invitations. Unfortunately, the number of guests does not always correspond to the number of RSVPed guests. Based on her experience, the wedding planner knows it is extremely rare for guests to attend a wedding if they notified that they will not be attending. Therefore, the wedding planner will assume that no one from these 50 invitations will attend. The wedding planner estimates that the each of the 25 guests planning to come solo has a 74% chance of attending alone, a 20% chance of not attending, and a 6% chance of bringing a companion. For each of the 60 RSVPs who plan to bring a companion, there is a 90% chance that they will…arrow_forward
