A marketing research company would like to be able to predict households' average monthly consumption of detergent. The company statistician tried to estimate the following regression model using data collected from 63 households: Y = a + B,X, +B.X; Where. Y is number of units of detergent (in ounce), X. is the price of detergent (per ounce) and X. is the number of members in a family. Part of the regression results are reported below Coefficients Standard error t-stat Intercept -2.59 3.49 -.072 X₁ -0.12 0.10 X₂ 1.89 3.86. Regression Sum of Square (RSS) 158 Residual Sum of Square (SSE) 209 (a) Fill out the missing values. (b) Find the value of R-qsuare and interpret it. (c) What is the value of adjusted R-square? (d) Which of the coefficients is/are statistically significant? e) Conduct an appropriate test to see whether the explanatory variables are jointly significant or not.
