The next three problems explore some techniques of data analysis.
According to the US Bureau of the Census, the world population in the year 1950 was A=2555360972, and in 2000 it was B=6079006982. We'll use A and B so we don't have to keep writing those large and idiosyncratic numbers. We usually use y and x in the equation of a line, but in this and the following problem let's use N and t instead. t stands for time and N for the size of the population.
If
N(t)=mt+b
such that N(1950)=A and N(2000)=B, then m= and and b= .
Suppose you want to estimate the population in 1975. To that end you compute N(1975) = . (Round your answers to the nearest integer. The process illustrated in this problem is called linear interpolation.)The next three problems explore some techniques of data analysis.
