The life expectancy for females in a certain country born during 1980−1985 was approximately 75.2 years. This grew to 76 years during 1985−1990 and to 76.2 years during 1990−1995. Construct a model for this data by finding a quadratic equation whose graph passes through the points (0,75.2),(5,76),and (10,76.2). Use this model to estimate the life expectancy for females born between 1995 and 2000 and for those born between 2000 and 2005.

Let x be the number of years since 1980 and y be the life expectancy for a person born between (1980+x) and

(1980+x+5). Find a quadratic equation whose graph passes through the points (0,75.2), (5,76), and (10,76.2).

**Y=?**

**According to the model, the life expectancy of a female
born between 1995 and 2000 in this country is ___?_
years.**

**According to the model, the life expectancy of a female
born between 2000 and 2005 in this country is __?__
years.**

Let x be the number of years since 1980 and y be the life expectancy for a person born between (1980+x) and (1980+x+5).

The quadratic equation that we want to estimate is

We have 3 data points and 3 unknowns.

the equation for (x=0,y=75.2) is

the equation for (x=5,y=76) is

the equation for (x=10,y=76.2) is

Subtracting the last 2 we get

Lastly we get the value of b using

the quadratic equation which passes through the points (0,75.2), (5,76), and (10,76.2) is

Ans:

The years 1995 and 2000 is (1980+15) and (1980+15+5)

That means x=15 for the years 1995 and 2000. Substituting x=15 in the equation we get

Ans: According to the model, **t**he life
expectancy of a female born between 1995 and 2000 in this country
is 75.8 years

The years 2000 and 2005 is (1980+20) and (1980+20+5)

That means x=20 for the years 2000 and 2005. Substituting x=20 in the equation we get

Ans: According to the model, **t**he the life
expectancy of a female born between 2000 and 2005 in this country
is 74.8 years

Can you predict the life expectancy for an individual born in
the United States in certain years?
Year of Birth: 1950; 1965; 1973; 1982; 1987; 1992; 2010;
2015
Life Expectancy: 70.2; 69.3; 71.4; 74.5; 75; 75.7; 78.7,
79.2
If you can make predictions, when year of birth is 1990, what
is the life expectancy? Please answer in a whole number.
If you can’t make a prediction, put the word "none" in the
answer box.

What is the approximate difference in life expectancy for people
born in rich nations versus people born in poor ones?

a) WHO is examining the improvement in life expectancy in an
underdeveloped country. Historical data for the population shows a
population mean life expectancy of 58.3 years, and with a
population standard deviation of 4.52 years. A recent sample of 75
people produced a sample mean of 60.8 years and a sample standard
deviation of 2.84 years. Evaluate H0: μ ≤ 58.3 and HA: μ > 58.3
