Regression Analysis: Computer Program Efficiency
Given regression equation: $$Y = 52.7 - 2.87X_1 + 0.85X_2$$
Where:
- Y = Processed requests per hour
- X₁ = Data size (gigabytes)
- X₂ = Number of tables
- Total sum of squares (TSS) = 1452
- Sum of squares due to regression (SSR) = 1143.3
- Standard error of b₂ = 0.55
- n = 7 observations
- Regression equation: $\hat{Y} = 52.7 - 2.87X1 + 0.85X2$ - Total Sum of Squares: $SST = 1452$ - Sum of Squares due to Regression: $SSR = 1143.3$ - Standard error of $b2$: $S{b2} = 0.55$ - Sample size: $n = 7$; number of predictors: $k = 2$ - Significance level: $\alpha = 0.05$ - Data table (Y, X...
