In a recent sales period, 50% of automobiles sold were manufactured by American companies, 40% were manufactured by Asian companies, and 10% were manufactured by European companies. Twenty percent of the American autos were SUV’s, 15% of the Asian autos were SUV’s, and 10% of the European autos were SUV’s. a. express the given information in a tree diagram b. if you randomly selected one auto sold during this time period find the probability that: i. it was an American SUV ii. it was an SUV iii. it was an American auto or an SUV iv. it was an American auto given that it was an SUV v. it wasn’t American given that it wasn’t an SUV

A cruise ship charges passengers $3 for a can of soda. Because of passenger complaints, the ship manager has decided to try out a plan with a lower price. He thinks that with a lower price, more cans will be sold, which would mean that the ship would still make a reasonable total profit. With the old pricing, the mean number of cans sold per passenger for a 10-day trip was 10.3 cans.

Suppose μ represents the mean number of cans per passenger for the new pricing. What hypotheses should the ship manager test if he wants to determine if the mean number of cans sold is higher for the new pricing plan?

A H₀: μ = 10.3 versus H_a: μ ≠ 10.3
B H₀: μ = 10.3 versus H_a: μ < 10.3    
C H₀: μ = 10 versus H_a: μ < 10
D H₀: μ = 10 versus H_a: μ > 10.3
E H₀: μ = 10.3 versus H_a: μ > 10.3

A thousand (1000) passengers in a cruise started having symptoms of a food poisoning after a dinner on the ship. They were rushed to a hospital that was using a relatively new test for Hepatitis A: The following data was available for the researchers: SICK PASSENGERS HEALTHY PASSENGERS TEST POSITIVE 480 TEST POSITIVE 50 TEST NEGATIVE 30 TEST NEGATIVE 440 510 490 Based on the data: Calculate: A) The sensitivity of the test. B) The specificity of the test. C) The false positives and false negatives.D) The predictive value+ E) The predicted value -F) The prevalence. G) The accuracy. Based on the results, do you think the test is useful in the diagnosis of Hepatitis A?

A cruise ship company is considering the purchase of 3 large ships for a total cost of $2,500,000. The company is also considering the purchase of 5 small ships for a total cost of $1,400,000. Both fleets would have estimated useful lives of 20 years. The discount rate for both alternatives is 9% Information regarding these two alternatives is as follows: 3 large ships 5 small ships Annual revenues (accrued) $500,000 $380,000 Annual expenses (accrued) $200,000 $180,000 Annual cash inflows $550,000 $430,000 Annual cash outflows $222,250 $206,350 Estimated salvage value $500,000 $0 The net present value of the purchase of the 3 large ships is: Select one: a. $3,081,097 b. None of the above c. $581,097

Question 8 t The profitability index of the purchase of the 3 large ships is: Select one: a. .46 b. 1.46 c. 3.0 d. None of the above Question 9 Not yet answered Marked out of 2.00 Not flaggedFlag question Question text The annual rate of return for the 3 large ships is: Select one: a. 0% b. 5% c. 12% d. 20%

Question 10 The internal rate of return for the 3 large ships is estimated to be 12%. True or False? Select one: True False

Question 11 a 7 year discounted payback threshold, the company would accept the purchase of the 3 large ships. Select one: True False

Question 12 a 7 year simple payback threshold, the company would accept the purchase of the 5 small ships. True or False? Select one: True False

OpenSeas, Inc., is evaluating the purchase of a new cruise ship. The ship will cost $500 million, and will operate for 20 years. OpenSeas expects annual cash flows from operating the ship to be $70 million and its cost of capital is 12%.

a. Prepare a NPV profile of the purchase. Do from rate 0% to 20% (please show me the formula you use, I have been trying to figure it out and cant)

b. Identify the IRR on the graph or calculate it from the data.

c. Should OpenSeas proceed with the purchase?

d. How far off could OpenSeas' cost of capital estimate be before your purchase decision would change?
