b. False

Answer 1

The question involves using statistical methods to calculate a regression equation for predicting the relationship between two variables and then using it to find predicted values.

Step-by-step explanation:

The student's question involves finding the regression equation to predict values of one variable based on another. This falls under the domain of statistics within mathematics and is typically a high school-level topic, where students learn about linear relationships between two variables.

Step-by-Step Explanation:

Plot the given data points on a scatter plot.

Calculate the slope (m) and y-intercept (b) of the regression line using the least squares method.

Form the regression equation ŷ = mx + b.

Use the regression equation to calculate predicted y-values (ŷ) for each x-value in the dataset.
