<h2>Hello!</h2>
The answer is:
The fourth option,
{s | s <90}
<h2>Why?</h2>Solving inequalities involves almost the same process of solving equalities for variable isolation.
We are given the inequality:
So, solving we have:
Hence, we have that the correct option is the fourth option:
{s | s <90}

Answer: b
Explanation:
The line of best fit to a scattergram is obtained in linear regression analysis by minimizing the sum of the squared errors.
For example, in the diagram shown below, there are n data points in the scattergram.
The error for the i-th data point is
