Question 8. For finding p-values, there are two approaches - bootstrap or use a distribution for the test statistic under the null hypothesis (like standard normal, T, Chi-Square, F). Using the distribution approach requires some assumptions (such as normality, or approximate normality, of the population distribution, large sample sizes, etc.)
For the following testing scenarios, write down the assumptions that are needed
a. Testing of equality of proportions between two categorical variables - p1 and p2.
Ho: p1 = p2 vs H1: p1 /= p2. Sample size n1 and n2
b. Testing for equality of proportions between three categorical variables using the Chi-Square Goodness of Fit approach
Ho: p1 = p2 = p3 vs H1: at least one pair of pi's is not the same. Sample sizes n1, n2, n3. Total sample size n = n1+n2+n3
a. Testing of equality of population means between three populations using the ANOVA table.
Ho: mu1 = m2 = mu3 vs H1: not all population means are the same Sample size n1, n2, n3

a. Determine the depreciation for each of the first two years by the straight-line method.
| First Year | Second Year |
| $ | $ |
b. Determine the depreciation for each of the first two years by the double-declining-balance method.
| First Year | Second Year |
| $ | $ |

8. Discuss the two methods used to incorporate risk into capital budgeting decisions.
In: Finance
A stock's current price on the London Stock Exchange is £8. There are two possible prices at the end of the year: £11 or £8. A call option to buy one share at £10 at the end of the year sells at £2. Suppose that you are told that a riskless portfolio can be created by selling 3 call options, buying 2 stocks today and borrowing £10 today.
(a) What is the risk free interest rate?
(b) Is the interest rate realistic in the UK? What values in the introduction of the question could explain such an interest rate?

Assignment 5 Directions: Read Chapter 8 of the text. This assignment will be divided in two parts (Part A and Part B), but will be submitted as one document - Make sure that you have also included the name of the assignment and your name on the assignment sheet. Text is FROM PRODUCTS TO SERVICES by Laurie Young.
· Part A. Differences in Product and Service Marketing Select 5 of the 10 subcategory descriptions of differentiating product and service marketing concepts found on pages 271-282 of the text, and compose a written report which highlights the difference between product and service marketing. Include either illustrations from the text or examples from your own experience that will provide support for your explanations. The assignment will be also assessed on proper spelling, grammar and paragraph organization. Part A should be a minimum of 3 pages in length (1.5 line spacing, 12 pt. type).
· Part B. Marketing Strategies There are 8 marketing strategies that are described on pages 289-301 of Chapter 8 of the text. Create a chart/table that summarizes the key points of this information that could be used as a quick reference for reviewing and selecting a marketing option. The chart/table should be organized to include the name of each strategy, a short description of each strategy, and one advantage and one disadvantage of each strategy. In addition to content, the assignment will be assessed on proper spelling and grammar, chart/table organization, labeling and identification. Write the answers on a word document and post it to the Dropbox Assignment 5 at D2L.
Discussion 3 Search the internet to find a marketing strategy that is NOT described on pages 289-301 of Chapter 8. Explain the strategy, advantages and disadvantages. Please include your source (e.g. the link of the website). Post your findings to the discussion board and Respond to your classmates

8. In MATLAB, the colon operator can be used in two ways: creating a matrix (or array) and selecting part(s) of a matrix (or array). Explain and give examples of each.
9. For a matrix C, that has 10 rows and 12 columns:
- What is the MATLAB command to select all of row 5 from it?
- What 2 MATLAB commands would ask the user for an integer, N, from 1 to 10 and then create an array D which is just row N from matrix C?
10. For matrix D, that has 5 rows and 8 columns:
- What does the MATLAB command Z=sum(D) do and what is the size (or dimensions) of Z?
