The model y = 100 + 2x1 - 4x2 + 8x3 is used to predict a company's sales (y) in a given quarter. x1, x2, and x3 are binary variables that represent quarter 1, quarter 2, and quarter 3, respectively. What is the predicted level of sales for quarter 2?
108, 100, 96, or 102
Homework Answers
Given model is,
y = 100 + 2x1 - 4x2 + 8x3
x1, x2 and X3 are binary variables that represent quarter 1, quarter 2 and quarter 3 respectively.
We want to predict the level of sales for quarter 2.
y = 100 + (2 * 0) - (4 * 1) + (8 * 0)
=> y = 100 + 0 - 4 + 0
=> y = 96
Therefore, the predicted level of sales for quarter 2 is 96

4. A researcher built a model to predict an indicator of fitness using heart-rate (X1), weight (X2), height (X3) and age (X4) as predictors. The model was Y = 4 - 1.2 X1 -0.5 X2 +0.6 X3-0.2X4. The standard errors for X1, X2, X3, and X4 were 0.4, 0.3, 0.5, and 0.06 respectively. 1. If SSR=15500, R2 is 0.333 and F-stat is 5, complete the ANOVA table. 2. Which of these variables is statistically the most significant? Why?
