The pooled estimator of p is a weighted average of the sample proportions from two groups. In this case, the two groups are ₁ and ₂. Therefore, the pooled estimator of p will be a weighted average of the sample proportion from ₁ (11eb12ba_eaa4_604c_94c2_c9bdfaf87a6d_TB6982_11) and the sample proportion from ₂ (11eb12ba_eaa4_604d_94c2_c105214e4df0_TB6982_11). Thus, the best choice is B.
