A recent 10-year study conducted by a research team at the Great Falls Medical School was conducted to assess how age, systolic blood pressure, and smoking relate to the risk of strokes. Assume that the following data are from a portion of this study. Risk is interpreted as the probability (times 100) that the patient will have a stroke over the next 10-year period. For the smoking variable, define a dummy variable with 1 indicating a smoker and 0 indicating a nonsmoker.

Xander, summer statistics intern in the Superintendent’s Office for the Palisades Point School District, wonders if the homerun teacher referrals in the 7th grade for two week periods are comparable. He tests this claim very preliminarily at the 1% significance level as a pilot study, and presumes that the distribution of referrals among these teachers is reasonably normal. He collects independent, simple random samples. The following data tables represent the numbers of referrals made by these seventh grade teachers:

Reba Dixon is a fifth grade school teacher who earned
a salary of 38,000 in 2018. She is 45 years old and has been
divorced for four years. She receives 1,200 of alimony payments
each month from her former husband. Reba also rent out a small
apartment building. This year Reba receive 50,000 of rental
payments from tenant and she incurred 19,500 of expenses associated
with the rental.
Reba and her daughter
Heather (20 years old at the end of the year) moved to Georgia in
January of this year. Reba provides more than one half of Heather
support. They had been living in Colorado for the past 15 years,
but ever since her divorced, Reba has been wanting to go back to
Georgia to be closer to her family. Luckily last December, a
teaching position opened up and Reba and Heather decided to make a
move. Reba paid a moving company 2,010 to move their personal
belongings, and she and Heather spent two days driving the 1,426
miles to Georgia.
Reba rented
a home in Georgia. Heather decided to continue living at home with
her mom, but she started attending school full time in January at
near by university. She was awarded a & 3000 partial tuition
scholarship this year and Reba help out by paying the remaining 500
tuition cost. If possible, Reba thought it would be best to claim
the education credit for these expenses.
Reba
wasn't sure if she would have enough items to help her benefit from
itemizing on her tax return, however she kept track of several
expenses this year that she thought might qualify if she was able
to itemized. Reba paid 5800 in state income taxes and 12500 in
charitable contribution during the year. She also paid the
following medical related expenses for herself and Heather :
Insurance premiums. 5,795
Medical care expenses 1,100

New contact lenses for Heather. 200
Shortly after the move, Reba got
distracted while driving and she ran into a street sign. The
accident caused 900 in damage to the car and gave her whiplash.
Because the repair was less than her insurance deductible, she paid
the entire cost of the repair. Reba wasn't able to work for two
months after the accident. Fortunately, she receives 2000 from her
disability insurance. Her employer, the central Georgia school
district, paid 60%of premium on the policy as a non-taxable fringe
benefits and Reba paid the remaining 40% portion.

2200 of interest income from corporate bonds and 1500 interest
income from city of Denver municipal bonds. Overall, Reba stock
portfolio appreciated by 12000 but she did not sell any of her
stock.
Heather reported 6200 of interest
income from corporate bonds she received as a gift from her father
over the last several years. This was Heather only sources of
income for the year. Reba had 10,000 of federal income taxes
withheld by employer. Heather made 1000 estimates tax payments
during the year. Reba did not make any estimate payments. Reba had
qualifying insurance for purposes of the affordable care Act
(ACA).

Yasmin Jamieson is 18 years old and is about to graduate from an Ottawa high school. She must decide: which university will she attend in September? She wants to follow a 4-year undergraduate degree in Economics. Yasmin has been accepted to attend McMaster University in Ontario, Canada, and Stanford University, California, United States. She faces only one annual cost for the each of the four years she is in university: tuition. Annual tuition at McMaster is $15,000. At Stanford, annual tuition is $45,000. Assume that she is not considering the option of working after high school. Therefore, do not consider the foregone labour earnings when going to university. After graduation, Yasmin has a strong interest in Labour Economics and hopes to receive job offers from Capital Economics (near Hamilton, Canada) and from Insight Economics (near Stanford, USA).
She knows that these two companies offer different annual salaries depending on where one has graduated. Capital Economics will offer a McMaster graduate an annual salary of $128,000 and a Stanford graduate an annual salary of $160,000. Insight Economics will offer a McMaster graduate an annual salary of $175,000 and a Stanford graduate an annual salary of $250,000.
Let’s assume the following:
• Yasmin’s objective in her decision-making is to maximize the present value of net future income over her career (that is, income net of costs).
• She is certain to get job offers from both companies.
• Please ignore differences between these two cities in terms of income taxes, the exchange rate, the cost of living and moving costs.
• These annual salaries do not change for the duration of her expected career, from age 22 to 65. Hint: this time horizon is sufficiently long to use the present value (PV) approximation formula.
• However, the present value of annual tuition costs should be calculated using the expanded present value formula.
• The market interest rate is 5%. Which university would you recommend to Yasmin? Please show all your calculations and explain your recommendation. (20 points)
