According to Food Consumption, Prices, and Expenditures, published by the U.S. Department of Agriculture, the mean consumption of beef per person in the year 2000 was 64 lbs. (boneless, trimmed weight). A sample of 40 people taken this year yielded the data provided in the attached data file named Assessment 10 Data. Analyze the data to answer the following question. 1. Construct an appropriate graph of the provided data. Someone has claimed that there are outliers in the data set. Is this true? 2. Two colleagues argue whether to include or exclude the outliers. Person A claims that if we are interested in learning how much meat is eaten by people who eat meat, the outliers should be omitted. Person B claims that if we want to learn how much meat is eaten on average by Americans, we much include Americans who might be vegetarians. 3. A point estimate of the mean meat consumption is? 4. Does the 95% Confidence Interval for the Mean contain the hypothesized value of 64.0? 5. What is the p-value associated with the hypothesis test of μ = 64 using α=0.05? 6. Should you reject the null hypothesis that the mean meat consumption is 64 lbs.? 7. Suppose the true meat consumption was 58 lbs. Calculate the power of the hypothesis test you just completed (e.g., the probability of rejecting the null hypothesis that μ=64 given the true mean is 58) 8. In general, as the sample size increases the power

XYZ Company has 40% debt 60% equity as optimal capital structure. The nominal interest rate for the company is 12% up to $5 million debt, above which interest rate rises to 14%. Expected net income for the year is $17,5 million, dividend payout ratio is 45%, last dividend distributed was $4,5/share, P0 = $37, g=5%, flotation costs 10% and corporate tax rate is 40%.

a. Find the break points

b. Calculate component costs (cost of each financing source)

c. Calculate WACCs.

d. Two projects are available: 1 st. Project requires 15 million initial investments, IRR=18% 2 nd. Project requires 10 million initial investments, IRR=12%

Please find the optimal capital budget. (Project(s) to be invested in)

Most Company has an opportunity to invest in one of two new projects. Project Y requires a $325,000 investment for new machinery with a six-year life and no salvage value. Project Z requires a $325,000 investment for new machinery with a five-year life and no salvage value. The two projects yield the following predicted annual results. The company uses straight-line depreciation, and cash flows occur evenly throughout each year. (PV of $1, FV of $1, PVA of $1, and FVA of $1) (Use appropriate factor(s) from the tables provided.)

4. Determine each project’s net present value using 7% as the discount rate. Assume that cash flows occur at each year-end. (Round your intermediate calculations.)

One year​ ago, your company purchased a machine used in manufacturing for $ 95 000 . You have learned that a new machine is available that offers many​ advantages; you can purchase it for $ 140000 today. It will be depreciated on a​ straight-line basis over ten​ years, after which it has no salvage value. You expect that the new machine will contribute EBITDA​ (earnings before​ interest, taxes,​ depreciation, and​ amortization) of $ 50 000 per year for the next ten years. The current machine is expected to produce EBITDA of $ 20 000 per year. The current machine is being depreciated on a​ straight-line basis over a useful life of 11​ years, after which it will have no salvage​ value, so depreciation expense for the current machine is $ 8 comma 636 per year. All other expenses of the two machines are identical. The market value today of the current machine is $ 50 000 . Your​ company's tax rate is 45 % ​, and the opportunity cost of capital for this type of equipment is 10 % . Is it profitable to replace the​ year-old machine?

4. Bayes Theorem - One way of thinking about Bayes theorem is that it converts a-priori probability to a-posteriori probability meaning that the probability of an event gets changed based upon actual observation or upon experimental data. Suppose you know that there are two plants that produce helicopter doors: Plant 1 produces 1000 helicopter doors per day and Plant 2 produces 4000 helicopter doors per day. The overall percentage of defective helicopter doors is 0.01%, and of all defective helicopter doors, it is observed that 50% come from Plant 1 and 50% come from Plant 2. [8 points]

(i) The a-posteriori probability of defective helicopter doors produced by Plant 1 is:

a. 0.0025

b. 0.025%

c. 0.25%

d. 0.015%

Clustering [4 Points]   

(ii)K-Means clustering algorithm

a. Needs K-means++ to know the optimal location of the centroids

b. Needs K-means++ to know the optimal number of clusters

c. Is a supervised algorithm

d. Provides the optimal clustering of points even if the initialization is bad
