Answer:
The equation of the regression line is:
Step-by-step explanation:
We have the following data:
We can use the Least Squares Regression to find the line of best fit for a set of paired data.
To find the line of best fit for <em>n</em> points:
Step 1: For each (x,y) point calculate and xy.
Step 2: Sum all x, y, and xy, which gives us Σx, Σy,
and Σxy.
Step 3: Calculate Slope b:
where <em>n</em> is the number of points.
Step 4: Calculate Intercept a:
Step 5: Assemble the equation of a line
Following the above steps we get:
Step 1: Find and xy as it was done in the table
Step 2: Find the sum of every column:
Step 3: Use the following equations to find a and b:
Step 4: Assemble the equation of a line
The graph of the regression line is:
