1. With a dotted line, extend your line of best fit to the year 2050. What do you predict the population to be for?
a) the world?
Ans.: the world population is rapidly increasing and I suspect that it will be about 9.8 billion people in 2050.
Ans.: likewise, Canada’s population is increasing. It will be approximately 44.1 million people in 2050.
