10.6 Suppose that Apex Health Services has four different projects. These projects are listed below, along with the amount of capital invested and estimated corporate and market betas:

1. Why do the corporate and market betas differ for the same project?
2. What is the overall corporate beta of Apex Health Services? Is the calculated beta consistent with corporate risk theory?
3. What is the overall market beta of Apex Health Services?
4. How does the riskiness of Apexs stock compare with the riskiness of an average stock?
5. Would stock investors require a rate of return on Apex that is greater than, less than, or the same as the return on an average-risk stock?

Please show all work, thanks!
