Life expectancy in the US varies depending on where an individual lives, reflecting social and health inequality by region. You are interested in comparing mean life expectancies in counties in California, specifically San Mateo County and San Francisco County. Given the data below, answer the following questions.

1. Calculate the standard error of the mean difference in male life expectancy between the 2 counties, assuming nonequal variance.

2. Calculate a 99% confidence interval for the mean difference in male life expectancy between the two counties. Use the conservative approximation for degrees of freedom.

3.Based on your confidence interval, would you expect the mean difference in male life expectancy to be statistically significant at the α=.01 level? EXPLAIN

How is adverse selection mitigated in the US system of care?

How might repealing the individual mandate affect adverse selection and insurance premiums?

When it was passed, part of the goal of the ACA was to decrease health care costs in the United States. Discuss the ways in which costs might be reduced and the ways in which costs might actually increase as a result of ACA.

How is adverse selection mitigated in the US system of care? How might repealing the individual mandate affect adverse selection and insurance premiums?

When it was passed, part of the goal of the ACA was to decrease health care costs in the United States. Discuss the ways in which costs might be reduced and the ways in which costs might actually increase as a result of ACA (There are several supplemental readings that are helpful for answering this question).

We have now looked at three different health care systems. Compare and contrast the American System with the Bismarck and Beveridge Systems. What are the strengths and weaknesses of each in your mind?

Suppose you are a middle-aged person with cancer. Your job doesn’t offer health insurance. Briefly explain how you might have been impacted by the implementation of the ACA.

You are 20 years old and have completed your BBA and want to pursue further education but you don’t want to take money from your father. Your plan is to start working and earn enough money so that you can finance your degree on your own and get yourself enrolled in five years’ time. You estimate that the annual cost of doing an MBA 5 years from today will be PKR 400,000 and the program will be two years long. You will need the money at the beginning your program so that you are not worried about how to clear your dues during your studies. Luckily you go for a job interview and they hire you and you start working at a salary of PKR 25,000. So you decide that 50% you will deposit in a saving account at a 10% rate with monthly compounding for your further studies and the remaining amount you will use for your daily expenses.

1. Will you be able to meet your goal at this current saving rate?
2. What percentage of your salary should you save if you want to have exactly your university expenses amount?
3. How would your answer to part 1 change if the saving account rate changed to 5%? Comment on your answer.
4. If you are given an option to invest at the 10% saving rate with monthly compounding or 10.5% semiannual compounding, which would you chose? Explain your answer

Give your opinion of the following issues associated with genetic testing: Define these terms: Genetics Genomics Pharmacogenomics Privacy and Confidentiality Who should have access to genetic information? Who owns and controls it? Discrimination Should employers be able to require job applicants to take genetic tests as a condition of employment? Equitable Access to Genomic Technologies Rare genetic conditions – Who will fund the development of treatments for genetic disorders that affect a relatively small number of people? Impact of Genetic Information How does a person’s genetic information affect that individual and society’s perception of that individual?

a) One child is age 10 and the other is age 15. Mr. OP’s earned income is $75,000 and Mrs. OP has no earned income. Their AGI is $81,300.

b) One child is age 2 and the other is age 6. Mr. Op’s earned income is $45,000 and Mrs. OP’s earned income is $28,000. Their AGI is $81,300.

9. On March 31, Mr. R quit his job with MT Inc. and began a new job with PK Company. His salary from MT Inc. was $53,900 and his salary from PK Company was $90,000. Compute his excess payroll tax withholding credit. (Assume a social security rate of 6.2% and a wage base limit of $137,700.)

10. Mr. and Mrs. K’s AGI was $23,000. Their federal income tax withholding was $850. They had no itemized deductions and two dependent children, ages 14 and 15. If they are entitled to a $5,828 earned income credit, compute their tax refund, including the. Include the refundable child tax credit, the earned income tax credit, and the federal income tax withheld in computing the tax refund.

Students enrolled in an introductory statistics course at a university were asked to take a survey that indicated whether the student’s learning style was more visual or verbal. Each student received a numerical score ranging from -11 to +11. Negative scores indicated a visual learner, and positive scores indicated a verbal learner. The closer the score was to -11 or +11, the stronger the student’s inclination toward that learning style. A score of 0 would indicate neutrality between visual or verbal learning. For the 36 students who took the survey, the mean score was -2.744, and the standard deviation was 4.988.

1. State the null and alternative hypotheses for testing whether the mean score (among all students at this university) differs from 0.

2. Calculate the value of the t-test statistic for the hypotheses stated in question 1.

3. Determine the p-value of the test as accurately as possible.

4. Summarize the conclusion that you would draw from this test.

5. Comment on whether the technical conditions of this t-test are satisfied.
