Module: Data AnalysisNameLesson: Line of Best FitDate______A student who waits on tables at a restaurant recorded the cost of meals and the tip left by single diners.Meal Cost$5.00$7.00$12.00$15.00$9.00Tip$0.50$1.00$1.50$2.50$2.00117157517272000Plot the points on the graph provided below, be sure to label the axes and provide a title for your graph. Draw one straight line through the data points that seem to match the trend in the data. Pick two points on your line (not the data points), and draw a circle around them. Find the slope between the two points. You may use a slope triangle (“stair”) or the slope formula Y2 -Y1 . X2 - X1 Slope: ______________Estimate your y-intercept:______________Put these (slope and y-intercept) together to make a linear equation in slope-intercept form. Equation: ___________ Now, use the calculator to determine the best fit line (linear regression) equation. Calculator’s regression equation: How close was your equation from step f to the calculator’s equation above? Why do you think this happened? If the next diner orders a meal costing $21.50, how much tip should the waiter expect to receive? Use both your equation and the calculator’s equation to help you figure this out.
