Consider the following data values of variables x and y. 
a.Determine the least squares regression line.
b.Find the predicted value of y for x = 9.
c.What does the value of the slope of the regression line tell you?
Least Squares Regression Line
A straight line that minimizes the sum of the squared differences between observed and predicted values in a dataset.
Slope
In the context of a linear equation, slope represents the rate of change between two variables, indicating how much one variable changes for a unit change in another variable.
Predicted Value
The estimated outcome based on a statistical model or regression analysis.
- Carry out calculations pertinent to the least squares estimation approach, involving the computation of the slope and y-intercept for the regression line.
- Understand the importance of the slope in a regression model within practical situations.
Verified Answer
