Question

A regression equation from an Indian bank: Ŷ = 2.5 + 0.8X₁ − 0.3X₂. p-values: α̂: 0.03, β̂₁: 0.02, β̂₂: 0.08. At 5% significance level, which is correct?

A All three coefficients are statistically significant; model fully reliable
B Intercept and β₁ are significant; β₂ is NOT significant at 5% — current account deficit does not significantly explain exchange rate stability in this model
C β₂ is most important since it has the largest economic impact regardless of p-value
D Since β₂ is insignificant, the model must be re-estimated dropping X₂ without any consequences
