A real simple way to see sensitivity analysis is with a perpetuity. Suppose that Gunney Highway Corporation is creating a new line of night vision goggles. The cost of the project today is $12.00 million. The project cash flow estimate is as follows: Year 1 Financial Data: Sales: $2,041,969.00 COGS: 49.00% of sales Depreciation: $1,000,000.00 The tax rate is 39.00%, while the cost of capital is 10.00%. Cash flows will have a growth rate of 0.00% going forward. a) What...

6. In the simple linear regression model, the y-intercept represents the:a. change in y per unit change in x.b. change in x per unit change in y.c. value of y when x=0.d. value of x when y=07. In the simple linear regression model, the slope represents the:a. value of y when x=0.b. average change in y per unit change in x.c. value of x when y=0.d. average change in x per unit change in y.8. In regression analysis, the residuals...

What is the real difference between between correlation and regression analysis? I see that correlation allows us to examine whether two variables exhibit some kind of association with each other. Does correlation mean means that one variable is dependent on another? Is this an example of correlation - Tips are dependent on the actual restaurant bill? Can you give other examples of correlation and regression? Thanks.

(a) Does a high value of ? 2 in a simple regression model imply that the two variables are causally related? Explain. (b) Compare and contrast mean and median as measurements of the center of a distribution. Under what circumstances, we should use one instead of the other as the measurement of the center of a distribution? Explain.
