1. You and a group of friends wish to start a company. You have an idea, and you are comparing startup incubators to apply to. (Start up incubators hold classes and help startups to contact venture capitalists and network with one another) Assume funding is normally distributed.

                      Incubator A has a 80% success ratio getting companies to survive at least 4 years from inception. The average venture funding of the 28 companies reaching that 4 year mark, is 1.3 million dollars with a standard deviation of 0.6 million

Incubator B has a 60% success ratio getting companies to survive at least 4 years from inception. The average venture funding of the 21 companies reaching that 4 year mark, is 1.9 million dollars with a standard deviation of 0.55 million

1. Are the success ratios significantly different?(note the count is given but not N, how do you find N?)

2. Is the average funding in incubator B significantly different from the average funding in a. (use a=0.01). Assume a normal distribution

A business investor is considering a new food venture on an isolated construction site. He has been given permission to operate on the site for a period of 15 years. He has compiled the following information about the new proposed business venture:

Startup equipment: $450,000

Working capital required for new kitchen: $105,000

Expected annual cash inflow from food sales: $375,000

Expected annual cash expenses associated with the new business: $250,000

Restaurant upgrade required after 5 years: $55,000

At the end of the 15-year period, the equipment would be sold for its salvage value of $125,000. The company is required to pay taxes at the rate of 30%. It will calculate depreciation using the straight-line method, but it will not use the salvage value when computing depreciation for tax purposes.

Required:

a) Assuming a 15% after-tax cost of capital, compute net present value (NPV) of the new venture.

b) On the basis of your computations should this business be opened or not.

a stream consisting of 44.6 mole% benzene and 55.4% toluene is fed at a constant rate to a process unit that produces two product streams, one a vapor and the other a liquid. The vapor flow rate is initially zero and asymptotically approaches half of the molar flow rate of the feed stream. Throughout this entire period, no material accumulates in the unit. When the vapor flow rate has become constant, the liquid is analyzed and found to be 28.0 mole% benzene.

(a)  

Sketch a plot of liquid and vapor flow rates versus time from startup to when the flow rates become constant.

(b)  

Is this process batch or continuous? Is it transient or steady-state before the vapor flow rate reaches its asymptotic limit? What about after it becomes constant?

(c)  

For a feed rate of 100 mol/min, draw and fully label a flowchart for the process after the vapor flow rate has reached its limiting value, and then use balances to calculate the molar flow rate of the liquid and the composition of the vapor in mole fractions.

FOX News surveyed voters, and according to their survey results, 38% of the voters in California voted for Mitt Romney, the Republican candidate for President in 2012 (source: “Presidential election results,” http://nbcnews.com, updated Feb. 9, 2016). A small startup company in San Jose, California, has ten employees. (Hint: Find out the distribution type)

a. How many of the employees would you expect to have voted for Romney? (5 points)

b. All of the employees indicated that they voted for Obama. Determine the probability of this assuming they are representative of all California voters. (5 points)

c. Eight of the employees voted for Obama. Determine the probability that at least 8 of the employees would vote for Obama if they are representative of all California voters. (2.5 points)

d. Based on your calculations in parts b and c, do the employees reflect the California trend? Support your answer with statistical calculations and reasoning. (2.5 points)

Please provide clear explanations for the answers. Thank you.

You are the practice manager for Dermatology Associates of Linwood (DAL): a multi-physician dermatology practice. Recently, the physician partners have decided to invest in purchasing an existing dermatology practice in a neighboring city, which will be operated under the group's name. They have asked you to research the financial logistics of acquiring this new location. The practice is fully-staffed, however the (one) physician owner is retiring, leaving an opening for a new physician to be hired. In keeping with DAL's standard of care, several new expenses will be incurred with the acquisition, including: access to DAL's electronic medical record system, a Fraxel laser, and new furniture for the waiting room area.

Draft a proposal, addressing the following items in a Word document:

• Summary of estimated primary startup costs (create a table to illustrate and organize this information)
• Financing options
• Summary of when the practice will reach profitability. Explain the finance principle you can use to make this determination. (You do not need to perform the calculations, but you do need to explain how to estimate and assess profitability).

One of Mary’s investments is going to mature, and she wants to determine how to invest the proceeds of $50,000. Mary is considering three new investments: a business startup fund (BSF), a one-year certificate of deposit (CD) with a guarantee of 4.5% return, or a communication technology stock called New 5 G Technology(N5G).

Mary estimates the return on BSF as 15%, 9%, -3% or -12%, and the return on N5G as 33%, 28%, -13% or -22%, depending on whether market conditions are excellent, good, average, or poor, respectively. Mary also has been collecting financial market information daily and estimates the probabilities of an excellent, good, average, and poor market to be 0.23, 0.20, 0.47, and 0.10, respectively.

TO Industries prepares monthly cash budgets. The following budget information is available for April and May 2020:

All sales are credit sales. The company expects to collect 65% from customers in the month of the sale and the remaining 35% in first month following the sale. The company purchases direct materials on account. The company pays for 70% of the purchases in the month of the purchases and the remaining 30% in the first month following the purchase. Direct labor, manufacturing overhead, and selling and administrative expenses are paid in cash in the month incurred.

Additional information:

• March 2020 credit sales were $600,000
• March 2020 purchases of direct materials were $200,000
• The company’s cash balance on April 1, 2020 is expected to be $90,000
• The company wants to maintain a minimum cash balance of $80,000 and has a line of credit in the amount of 1,000,000, with an annual interest rate of 6%, available to borrow if the budgeted cash balance falls below that level. Any amounts borrowed on the line of credit at the end of a month require a cash interest payment in the subsequent month. If the ending cash balance in a month exceeds the minimum balance, the excess amount is used to repay any amounts borrowed on the line of credit.

Required

1. Prepare a schedule of cash collections from credit sales for April and May 2020.
2. Prepare a schedule of cash disbursements for direct material purchases for April and May 2020.
3. Prepare a cash budget for April and May 2020 in columnar format.
