Author, Hossein Zare, PhD Citation: Zare, H. (2019). HMGT 400 Research and Data Analysis in Health Care. FINAL EXAM. UMGC.EDU Question #1 (15 credits): [RStudio Users and Excel Users] The FINAL EXAM dataset, provides some information about hospitals in 2011 and 2012, download the FINAL EXAM data and then complete the descriptive table. Please answer the following questions. A) In term of hospital characters what are the significant difference between 2011 and 2012? B) In term of socio-economic variables what are the significant difference between 2011 and 2012? To report the “Per Capita Hospital Beds to Population”, you need to divide “total_hospital_beds/ tot_population) C) Based on your findings in which years hospitals had better performance? How hospital performance related to hospital characteristics and socio-economic characteristics? Please write at least three main different movements between 2011 and 2012. Table 1.

Which test is the best fit test? Why? 3) Use a box-plot and compare Hospital net benefit between for-profit and non-for-profit hospitals. 4) Show another scatter plot and compare hospital cost (x-axes) and revenue (y-axes) and discuss your findings? 5) Comparing hospital net-benefit which hospitals has better performance? To answer this question first compute the hospital net benefits with subtracting hospital costs and revenues and then use ttest to compare the significant differences between FP and NFP hospitals. 6) Overall, what are the main significant differences between for-profit and non-for-profit hospitals?

Please remember for the class exercise you used the herf_cat as a hospital Herfindahl index. For this question make sure to use herf_ins as Herfindahl index for insurance market. Use the final exam dataset and then answer the following questions: 1) In a short paragraph explain the Herfindahl index you can use the reference provided in the class exercise or any other citation. 2) Compare the following information between hospitals located in high, moderate and low competitive health insurance markets? o 2.1. What are the main significant differences between hospitals in different markets? (use Anova test) o 2.2. What is the impact of being in high-competitive health insurance market on hospital revenues and cost? o 2.3. Do you think being in high-competitive market has positive impact on net hospital benefits? o 2.4. What about the number of Medicare and Medicaid discharge? Do you think hospitals in higher completive market more likely to accept more Medicare and Medicaid patients? o 2.5. What is the impact of other variables? (Note: to answer to the last question, please compute the ratio-Medicare-discharge and ratio-Medicaiddischarge first and then run 2 ttest) high vs. moderate and high vs. low competitive market), please support your findings with box-plot).
