Sagot :

We will have the following.

First, we will have that the graph generated from the data will be:

Then, we will have the following:

a) Using the least squares linear regression method we will have that the line of best fit will be given by:

[tex]y=0.12694x-7.2283[/tex]

This can be seeing as follows:

c) Now, we will have that the approximation for the hourly wage in 2025 will be:

[tex]\begin{gathered} f(125)=0.12694(125)-7.2283\Rightarrow f(125)=8.6392 \\ \\ \Rightarrow f(125)\approx8.64 \end{gathered}[/tex]

So, the approximate hourly wage in 2025 will be $8.64.
