Solutions

Expert Solution

Regression

Regression Model

Year = 2070.952 – 49.568*Growth Rate

When X = 0

Year = 2070.952 – 49.568*0 = 2070.9 ~ 2071

Regression Model 2

Regression Model

Year = 2051.06 – 17.66* Fertility Rate Children per Woman

So, When Fertility Rate Children per Woman = 2.2

Year = 2051.06 – 17.66*2.2 = 2012.22

So, in Year 2012.22, Womens Fertility rate is expected to be 2.2 and

By 2071, World’s Population Growth would be 0.
