Quizplus · Accepted Answer

The line of best fit is calculated using the least squares method, which finds the line that minimizes the sum of the squared differences between the observed values and the values predicted by the line. Based on the given data, the equation $y = 5.05 + 1.91x$ best represents the relationship between productivity and dexterity.
