The machine has a dial that sets the length of the bars to be cut. However, the dial is currently out of alignment and the plant manager is collecting data to assess the situation. The following table shows 8 trials at different dial settings along with the actual output length of the bars that were cut. All measurements are in millimeters. a. Use the following grid to construct a scatterplot in which dial setting is the explanatory variable and output length is the response variable. Based on your graph, does a linear model seem appropriate? Justify your answer. b. Use the data to construct a least-squares regression line to predict output length from dial setting. c. Assume that all conditions for inference are met. Indicate the hypotheses appropriate to test whether there is a linear relationship between output length and dial setting. d. The test statistic for the appropriate test is…arrow_forwardA water tower (W) supplies two towns Amherst (A) and Kenmore (K) with water.
