Question

Part (circle A study compared the quantity of soap with the height of soap suds created in a standard dishpan. Recorded below are the results of 10 cases where the amount of soap is measured in grams and the response, the heights of soap suds, is measured in millimeters. 1. 1. a 2. a Soap (gm) Suds (mm) 3.5 4.0 4.5 5.0 5.5 6.0 6.5 7.0 7.5 8.0 24.4 32.1 37.1 40.4 43.3 51.4 61.9 66.1 77.2 4. a 5. a 6. a a) Use technology to find the equation of the least squares regression line for predicting the height of the suds from the amount of soap used. b) Find the residual for the case with 5.5 grams of soap and 43.3 mm of suds. Show your work. c) Interpret the slope in terms of the problem situation. (use complete, neatly written sentences) d) Give an example of extrapolation in this situation. (use complete, neatly written sentences)
