The best estimate for the elk population can be calculated as follows:
(No. of marked elk in first sample * Total no. of second sample) / No. of marked elk in second sample = (75 * 250) / 15 = 1250
Therefore, the best estimate for the elk population is B. 1,250.
(No. of marked elk in first sample * Total no. of second sample) / No. of marked elk in second sample = (75 * 250) / 15 = 1250
Therefore, the best estimate for the elk population is B. 1,250.
