Answer the following question using R:

(a) Use linear regression to estimate the GDP of the missing years 1955 and 1960. Use the Population estimate for the missing years found using M1.

(b) Create a new data frame showing Population and GDP from 1947 to 1964 including the values for 1955 and 1960 predicted by regression models M1 and M2.

(c) Use this data frame (b) to plot the GDP and Population in a scatter plot for the years 1947 -1964, clearly marking the missing years in the original data
