Chapter 2.3, Problem 89PE

(a)

To determine

To graph: The scatter plot that represents the data as a set of six points in the rectangular coordinate axis, where x represent the number of birth years after $1960$ and y represents male life expectancy. The bar graph for American men and women life expectancy born in six selected years is shown below,

(b)

To determine

The linear function that models the life expectancy $E\left(x\right)$ of the men born x years after $1960$ with the help of the coordinates on the scatter plot for the years $1980$ and $2000$, also draw a line through the two points which shows the life expectancy of the men in $1980$ and $2000$.

(c)

To determine

To calculate: The life expectancy of a men born in $2020$ in America, where the formula that models the life expectancy of the men in Americaafter $1960$ is $E\left(x\right)=0.215x+65.7$.
