Adrienne Bergen ECO 550 MANAGERIAL ECONOMICS AND GLOBALIZATION ASSIGNMENT 1 30 OCTOBER 2013 Multiple Regression. Kitchen Products, Ltd. is a regional distributor of the Kitchen Regal Bread Making Machine. The company wishes to assess the relative importance of price reductions versus an increase in personal selling efforts as means for enhancing product promotion. To this end, the company recently used a regression analysis approach to study the following monthly unit sales, price, and personal selling expense information for the Bozeman, Montana market: Unit Sales | Price | Personal Selling Expenses (PSE) | 132 | $74 | $1,140 | 203 | 74 | 1,400 | 217 | 55 | 1,160 | 255 | 53 | 1,210 | 252 | 64 | 1,490 | 239 | 70 | 1,460 | 152 | 75 | 1,200 | 197 | 58 | 1,020 | 230 | 65 | 1,390 | 154 | 61 | 1,040 | As a first step in the analysis, the company ran simple regressions of unit sales on each of the potentially important independent variables of price and personal selling expenses: The first simple regression equation is: Equation 1: SALES=371-2.59PRICE Predictor | Coef | Stdev | T ratio | P | Constant | 371.0 | 109.5 | 3.39 | 0.010 | Price | -2.587 | 1.676 | -1.54 | 0.161 | SEE = 40.94 R2 = 22.9% IP = 13.3% As a second step in the analysis, the company ran a second simple regression equation; the second equation is: Equation 2 : SALES = 5.9 + 0.158 SELLEXP Predictor | Coef | Stdev | t ratio | p | Constant | 5.89 | 90.10 | 0.07 | 0.949 | SELLEXP | 0.15764 | 0.07142 | 2.21 | 0.058 | SEE = 36.77 R2 = 37.8% R2 = 30.1% A. Based on these simple regression model results, does the potentially important independent variable affect unit sales? * For the first simple regression line for Price versus Sales, R2 = 22.9% means 22.9% of the total variations in Sales are counted for or explained
