1. What are the main significant differences between hospitals in/across different markets? (use ANOVA test)
2. Using the density curves/box plots, compare hospitals' cost and revenues between/across three markets.
3. What is the impact of being in a high-competitive market on hospital revenues and cost? Do you think being in a high-competitive market has a positive impact on hospital net benefits? What about the number of Medicare and Medicaid discharges? Do you think hospitals in a higher competitive market are more likely to accept more Medicare and Medicaid patients?
4. What is the impact of other variables?

Please talk about your findings in 2 paragraphs.

(Note: to answer to the last question, insert 2 new columns and please compute the Medicare-discharge ratio and Medicaid-discharge ratio first (i.e., Medicare Discharges Total Discharges; Medicaid Discharges Total Discharges), then run 2 t-tests (i.e., high vs. moderate and high vs. low competitive market). Please support your findings with box-plot).
