Step 1
Since x is measured in inches and y is measured in pounds, we need to convert the slope to a linear scale. We can do this by dividing x by 1000 and y by 1500. Now, we can use this information to calculate the slope of the regression line. The slope of the Show more…

Assume that the two variables x and y are related according to the simple linear regression model. Summary quantities are n = 15, Σy = 582, Σy² = 23640, Σx = 53, Σx² = 167.42, and Σxy = 1687.9. Calculate the least squares estimate of the slope and intercept.
