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 female life expectancy. The bar graph for American men and women life expectancy born in six selected years is shown below,

Solution Summary: The author illustrates the linear function that models the life expectancy of American men and women in six selected years.
Definition Definition Representation of the direction and degree of correlation in graphical form. The grouping of points that are plotted makes it a scatter diagram. A line can be drawn showing the relationship based on the direction of points and their distance from each other.

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 female 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(x) of the women born x years after 1960 with the help of the coordinates on the scatter plot for the years 1970 and 2000, also draw a line through the two points which shows the life expectancy of the women in 1970 and 2000.
(c)
To determine
To calculate: The life expectancy of a women born in 2020 in America, where the formula that models the life expectancy of the women in Americaafter 1960 is E(x)=0.167x+73.03.
