Problem 1. The following is the estimation results for a multiple linear regression model: Y = Bo + BIX1 + B2X2 +E SUMMARY OUTPUT Regression Statistics R-Square 0.612 Standard Error of Regression (S) 793.253 Observations 41 Coeff StdError t-Stat Intercept 1097.000 326.000 3.370 X1 23.387 7.393 X2 0.909 0.319 Questions: 1. Use the fitted model to make a prediction for Y when X1 = 0.17 and X2 = 0.88 (5 points). 2. Calculate the t-stats for the slope 1 (5 points). 3. Calculate the 95% confidence interval for the slope 2 (10 points). 4. Are these two slopes statistically significant at 5% significance level (10 points)
