The Case Study
The United States has one of the highest healthcare costs in the world, spending trillions of dollars on
healthcare, which typically exceeds $10,000 per individual. Studies report that healthcare costs have gone up
from 5% of gross domestic product (GDP) to 18% during the period 1960 to 2018. Moreover, a number of
articles have suggested that predisposing personal characteristics, such as income, age, state, job etc. could
possibly be related to the cost of health services.
“The Americans dying because they can't afford medical
care - A December 2019 poll conducted by Gallup found
25% of Americans say they or a family member have
delayed medical treatment for a serious illness due to the
costs of care.”

“Young people, who are expected to benefit from lower premiums should the GOP repeal-and-replace efforts
succeed, already pay the least. But even their costs can be considerable, depending on where they live. In
2016, the financial data site ValuePenguin found that the average costs for coverage for a 21-year-old go from
$180 a month in Utah, plus a $2,160 deductible (potentially $4,320 a year, total), to $426 a month in Alaska,
with a $5,112 deductible (potentially $10,224 a year, total).”

“Average annual costs per person hit $10,345 in 2016. In 1960, the average cost per person was only $146 —
and, adjusting for inflation, that means costs are nine times higher now than they were then.”

“Americans pay a lot for healthcare. Depending on where they live, typical workers shelled out between
$4,500 and $8,300 for healthcare in 2017. But the US government pays even more.”

The UnitedHealth Group: America’s most prominent health insurance provider aims to identify the
characteristics of the population to improve their understanding of the potential influence of these
characteristics on their high medical costs billed by an insurance provider. They have access to a sample of US
Health Insurance data containing 1338 insured personnel with their Age, Sex, Body Mass Index, Number of
Children, Smoking status, Region and Insurance charges.

Subject: Analysis of US Health Insurance data
As per our conversation, I have spoken with our reporting team and we have following questions relating to
the US health insurance data. Please complete the following analysis for me. Your responses will assist
them in writing the feature section of our next issue.
1. Provide your insights on how the specific attributes of the whole insured population is affecting their
insurance premiums based upon our sample data:
(a) An estimate of the difference in medical costs for a female versus a male
(b) An estimate of the difference in medical costs for a single person versus someone with a family
(c) Males with no dependents have claimed that they have, on average, been charged more than
their female counterparts. Can you check whether this claim is possibly true?
(d) We would also like to know if there is gender bias in smoking behaviours. Specifically, is there a greater
proportion of males who are smokers compared to females? Can you check whether this claim can
also be substantiated? Briefly advise the findings in regard to the proportion of males and females who
2. Can you further analyse to see whether the beneficiary's residential area
egion in the US affect how
health insurance provider bill their medical costs?

primary beneficiary (young adults: 18 to 35 years; middle age: 36 to 55 years; and older adulthood:
