Calculate the arithmetic mean. Explain the term arithmetic mean. When is this calculation useful?
Calculate the geometric mean. Explain the term geometric mean. When is this calculation useful?
Question 2
Cross Country Camping and Hiking Company has two alternatives for an expansion. Alternative A has an expected return of 18% with a standard deviation of 6. Alternative B has an expected return of 17% and a standard deviation of 6.5.
Calculate the coefficient of variation for each of the alternatives.
When is the coefficient of variation a useful measure in assessing two or more alternatives?
Question 3
Sharon Smith’s portfolio contains three different financial assets. Common stock of Cornwallis Hotel Company represents 23% of the value of the portfolio; Pizza Company represents 42%; and Seaman’s Beverages represents the remaining 35%. The beta of Cornwallis Hotel is 1.2. Pizza Company has a beta of 1.9 and the beta of Seaman’s Beverages is .6.
Calculate the beta for Sharon’s portfolio.
