Step 2

Part a

Let x represents the number of births since year 1960 and y represents the male life expectancy.

Now, plotting the given data with respect to the year 1960 and we get.

Step 3

Part b

For the year 1980

x = 1980 – 1960 = 20 and y = 69.9

for the year 2000

x = 2000 – 1960 = 40 and y ...
