A survey with 30% missing data uses multiple imputation (M = 5). The point estimates of mean household income across 5 completed datasets are: $\bar{Q}_1 = 52,000, \bar{Q}_2 = 51,500, \bar{Q}_3 = 52,500, \bar{Q}_4 = 51,800, \bar{Q}_5 = 52,200$. The within-imputation variance (averaged over imputations) is $\bar{U} = 1,200,000$ and between-imputation variance is $B = 40,000$. By Rubin's formula, total variance is: $T = \bar{U} + \left(1 + \frac{1}{M}\right)B$

What is the total variance estimate?
