Hospital personnel routinely examine patient records for error, such as incomplete insurance information, on incomplete patient history, or missing/incomplete medical records. On average, about 270 new patients are admitted each day. Historically, about 8% of these records have contained errors. If a random sample of 40 new patient records is checked each day, what is the probability that this sample will contain at least two patient record with missing information?

Write an array method to carry out each of the following tasks for an array of integers. Note: you can think of each as a separate problem independent of the others.

1. a) Swap the first and last elements in the array.

2. b) Shi< all elements by one to the right and move the last element into the first

   posi>on. For example, 1 4 9 16 25 would be transformed into 25 1 4 9 16.

3. c) Replace all even elements with 0.

4. d) Replace each element except the first and last by the larger of its two neigh-

   bors.

5. e) Return true if the array contains duplicate elements (which need not be adja-

   cent).

Aria Acoustics, Inc. (AAI), projects unit sales for a new seven-octave voice emulation implant as follows:

Production of the implants will require $1,950,000 in net working capital to start and additional net working capital investments each year equal to 20 percent of the projected sales increase for the following year. Total fixed costs are $4,100,000 per year, variable production costs are $264 per unit, and the units are priced at $402 each. The equipment needed to begin production has an installed cost of $18,300,000. Because the implants are intended for professional singers, this equipment is considered industrial machinery and thus qualifies as seven-year MACRS property. In five years, this equipment can be sold for about 25 percent of its acquisition cost. The tax rate is 24 percent the required return is 15 percent.

MACRS schedule:

a. What is the NPV of the project?

b. What is the IRR?

b.)What is the IRR?

Product A is the end item and is made from 3 units of component B and 4 units of component C.

Component B is made from 2 units of component D and 2 units of component E. Component C is made from 2 units of component F. Lead times are as follows: A = 1 weeks, B = 2 weeks, D = 1 week, and E = 1 week.

A) Draw the bill of materials for Product A. (2 points)

B) Develop the MRP schedule for Product A and components B, D, and E only, given the gross requirement of product A. Currently, there are 50 units of B and 70 units of D on hand. No safety stock requirement.

1. The U.S. Census Bureau computes quarterly vacancy and homeownership rates by state and metropolitan statistical areas. The following data are the rental vacancy rates in percentage (%) grouped by region for the last quarter of 2018 using a sample of 4 statistical metropolitan areas.

                                     Vacancy rates (%)

1. You are hired as statistician to test whether there are any differences among the regions regarding vacancy rates and you should allow for 10% error.
2. Do you think that the mean vacancy rate is the same for these regions? Why

Your firm is evaluating a new $725,000 investment opportunity with a 16% required return. You expect to sell 3,500 units per year at $50 net cash flow each for the next 8 years. Suppose that after one year, you will know more about demand and be able to revise your estimate of future unit sales based on sales you observe for year 1. Further, suppose that the project can be dismantled and sold to net $650,000 at that time.

a. What is the minimum level of unit sales for year 1 below which would it make sense to abandon the project?

b. If the original expectation of 3,500 unit sales is the average of two equally likely outcomes (3,000 units or 4,000 units), what is the value of the project, including the option to abandon at the end of the first year?

Research Scenario: You have been raising Bombina orientalis, or Oriental fire-bellied toads, and measured the frogs’ jumps in centimeters. Your latest study looks at males and females’ reactions to being raised in a room with another animal. You set up three terrariums, each with six male and six female frogs. Each terrarium is in a separate room. Let A1 = male frogs, A2 =female frogs, B1 = frogs raised in a room with a dog, B2 = frogs raised in a room with a cat, and B3 = frogs raised in a room with a parrot.

3. What is the value of F for the two main effects?

4. Is there a significant main effect of roommate? Explain and support your position.

5. Is there a significant main effect of gender? Explain and support your position.

6. Is there a significant interaction between the sex of the frogs and the species of roommate? Explain and support your position.

This part of the assignment is purely conceptual with no computations required. Explain the following with references to the required readings:

What is likely to happen to interest rates if the rate of inflation suddenly increases?

Suppose there are two bonds each with coupon payments of $50. The first bond pays $1,000 in five years, and the other one pays $1,000 in ten years. If interest rates increased, would the value of the bonds increase or decrease? Which of the two bonds would have their value change more after the increase in interest rates? Explain your reasoning.
