Using the results for Model 1, what is the coefficient of determination? 0.1431 0.0205 0.0192 9789.29 10) Excel Exercise. Using the results for Model 1, interpret the coefficient estimate on the independent variable.The mileage increases by about 17 miles for each $1 increase in the price. The mileage decreases by about 0.17 miles for each $1 increase in the price. The price increases by about 17 cents for each extra mile. The price decreases by about 0.17 dollars for each extra mile. 11) Excel Exercise. Using the results for Model 1, for a car with 30,000 more miles, what happens to the price?The price increases by about $5000 The price decreases by about $5000 The price increases by about $25,000 The price does not change 12)  Excel Exercise. Which variable has the strongest negative correlation with price?Milage Cylinder Doors Cruise 13) Excel Exercise. Which statement best interprets a p-value?This is the probability that the lower bound of the hypothesis test will be found from the sample data. This is the probability that, given the null hypothesis is true, one would find a test statistic of this size. This is the probability that, given the null hypothesis is true, one would find a test statistic at least 10 percent larger than this number. This is the probability that one would find this test statistic in the t-table at the back of the book. 14) Excel Exercise. How many observations are in this data set?803 805 800 804 15) Excel Exercise. Using the results for Model 2, what is the F- statistic? (Round to 2 decimals.)1.23 95.40 106.80 7323.16 16) Excel Exercise. Using the results for Model 2, what does the F-statistic test?it tests if all the coefficients on the RHS variables are jointly zero This is the probability that, given the null hypothesis is true, one would find a test statistic of this size. it is the degrees of freedom for the sum of squares regression variation it is the mean square variation of the regression. 17)  Excel Exercise. Using the results for Model 3, what is the coefficient of (multiple) determination (round to 4 decimals)0.9288 0.8627 0.8608 Cannot tell 18) Excel Exercise. Using the results for Model 2, how should we interpret the coefficient on Cylinder?Larger engine size decreases the price. Larger engine size increases the price. Larger engine size increases the size of the car. Cannot tell from the sign of the coefficient. 19)  Excel Exercise. Using the results for Model 3, what does the intercept tell us?Holding all other variables at zero, the value of a car is about $8,100 Increasing all variables by 1 unit, increases the value of the car by about $8,100. The slope of the first x variable. Nothing. 20) Excel Exercise. Using the results for Model 3, what does the coefficient on Cadillac mean?A Cadillac is worth $15,500 less than any other car with all the same other features. A Cadillac is worth $15,500 more than any other car with all the same other features. A Cadillac is worth $15,500 more than a Saturn with all the same other features. A Cadillac is worth $15,500 less than a Saturn with all the same other features.              Math Statistics and Probability ECO MISC Share QuestionEmailCopy link Comments (0)

over 35,000 citizens, with a high percentage being older Americans who have retired to this area of the country. The hospital administrator has asked the Vice President of Risk Management to attend a meeting with the senior staff next week in the Board Room. The hospital administrator has asked Vice President of Risk Management to present areas of opportunity for increasing the hospital's risk management strategies to ensure a litigation-free environment for the facility, its patients, and its employees.During the meeting, the Vice President of Risk Management reports that all the continuous quality improvement (CQI) minutes for the past 3 months of meetings have been reviewed. Although most areas are being adequately resolved, there are some that need more attention, especially from the senior staff. Before specifically addressing those points, the Vice President of Risk Management briefs the staff on the major areas of risk for the hospital. They are:1. Employee-driven adverse actions against the facility 2. Medication errors3. Surgery/Treatment errors4. Patient falls5. Patient elopements6. Security breaches in secured areas7. Inaccurate coding and billing for government/insurer reimbursementsNow that the senior staff is aware of the major areas of risk concern, you, as the administrator in charge of all hospital business operations, assign each of these areas of concern to the respective director, such as the Directors of Human Resources, Nursing, Medical, Social Services, and Facility Security. Their reports of assessment, along with recommendations for achieving full compliance and reducing the hospital's litigation exposure, are due at the end of the month.Questions:1. While this situation has many areas of risk that are considered a top priority, focus on patient privacy and information disclosure (HIPAA violations). Which department is responsible for leading the initiative? As the administrator, describe your approach for managing this directive. Do you create a special projects team? How do you gather pertinent data for a category? What tools would you use?2. How do you determine if you are meeting the industry standards for this area of risk?3. Would you change any current policies or procedures? How and why?4. How would you train the affected staff with regard to this area of risk?5. What are the sanctions, penalties, or government investigations that could present a worst-case scenario if not addressed?
