Identify the two procedures that can be used to compute the Spearman correlation.
There are two risky shares, where you have calculated the means, and the correlation coefficient of returns between the two shares.
Sketch the mean-variance efficient frontier for portfolios of the two shares when the correlation coefficient is +1 and 0 respectively. Explain the shape of the frontier using algebra.
A 2012 suvey conducted by Idea Works provided data showing the percentage of seats avail- able when customers try to redeem points or miles for free travel. For each airline listed, the column labeled 2011 Percentage shows the percentage of seats available in 2011 and the column labeled 2012 shows the correponding percentage in 2012 (The Wall street Journal, May 17, 2012).
Develop a scatter diagram with 2011 Percentage as the independent variable.
What does the scatter diagram developed in part (a) indicate about the relationship
between the two variables?
Develop the estimated regression equation.
Test for a significant relationship. Use α = 0.05.
Did the estimated regression equation provide a good fit?
