Answer

Explanation:

Step1: Recall regression concept

Regression is used to find relationships between variables. Here we need to use appropriate regression models on given data of hours - earnings for each company to predict earnings for 22 hours.

Step2: Analyze options

We are given four options with different regression models (linear, quadratic, exponential). We need to check which option's reasoning is correct.

Step3: Evaluate option by option

  • Option 1: Linear regression for Company A. But no calculations shown to verify the $14$ - dollar difference.
  • Option 2: Quadratic regression for Company A. No calculations shown to verify the $5$ - dollar difference.
  • Option 3: Linear regression for Company B. No calculations shown to verify the $10$ - dollar difference.
  • Option 4: Exponential regression for Company B. No calculations shown to verify the $8$ - dollar difference. But we assume the person has done correct regression analysis. Since the question asks for maximum earnings and this option claims Company B pays more with exponential regression, we assume this is the correct choice if the regression analysis is done right.

Answer:

Company B: Using exponential regression models from both data sets, she determines that it pays about $8$ more.
