1. Estimate the regression equation for (a) setup costs and number of setups and (b) setup costs and number of setup hours. You should obtain the following results:Regression 1: Setup costs = a + (b A? Number of setups)Regression 2: Setup costs = a + (b A? Number of setup-hours)2. On two different graphs plot the data and the regression lines for each of the following cost functions. a. Setup costs = a + (b A? Number of setups) b. Setup costs = a + (b A? Number of setup hours)3. Evaluate the regression models for ?oNumber of setups?? and ?oNumber of setup-hours?? as the cost driver according to the format of Exhibit 10-18.4.Based on your analysis which cost driver should Tilbert Toys use for setup costs andwhy?
