Answer
$P = 1129.2019 \cdot (1.01693^t)$
According to the model, the estimate of the population in 1993 is $~~5381~million$
According to the model, the estimate of the population in 2020 is $~~8466~million$
Work Step by Step
When we input the data from the table from $t = 50$ to $t = 110$, the exponential regression function returns the following equation:
$P = 1129.2019 \cdot (1.01693^t)$
We can estimate the population in 1993:
$P = 1129.2019 \cdot (1.01693^t)$
$P = 1129.2019 \cdot 1.01693^{93}$
$P = 5381$
According to the model, the estimate of the population in 1993 is $~~5366~million$
We can estimate the population in 2020:
$P = 1129.2019 \cdot (1.01693^t)$
$P = 1129.2019 \cdot (1.01693^{120})$
$P = 8466$
According to the model, the estimate of the population in 2020 is $~~8436~million$
