The Hardest Interview 2 |work| ❲High Speed❳

Set (\Delta U = 0) → threshold (p_\textthresh = 2\lambda).

If (\Delta U < 0), they stop even if formal stopping rule not met (early stop). [ U_\texttotal = \sum_\textfamilies \left( \fracb_fg_f - \lambda \cdot t_f \right) ] the hardest interview 2

This creates negative feedback: If boys exceed girls nationally, (p_n < 0.5), and vice versa. At each step, before having another child, the family estimates current national ratio (\hatR) using: Set (\Delta U = 0) → threshold (p_\textthresh = 2\lambda)

[ R_n = \fracB_nG_n,\quad B_n = B_n-1 + X_n,\ G_n = G_n-1 + (1-X_n) ] where (X_n \sim \textBernoulli(p_n)). and vice versa. At each step

where (b', g') are updated after one more child, assuming (p_n) based on their estimate (\hatR).
