Welcome back Cosmas — missed you this week. Here's the solution for question 15. Step 1: Identify the given information. • Initial number of crayfish caught and marked (M) = 50 • Total number of crayfish caught in the second sample (C) = 50 • Number of marked crayfish in the second sample (R) = 3 Step 2: State the formula for the capture-mark-release-recapture method (Lincoln-Petersen Index). The estimated population size (N) is given by the formula: N = (M × C)/(R) Step 3: Substitute the given values into the formula. N = (50 × 50)/(3) Step 4: Calculate the estimated population size. N = (2500)/(3) N ≈ 833.33 Step 5: Round the population size to a whole number, as population counts must be integers. Since we cannot have a fraction of an organism, we round to the nearest whole number. The estimated number of crayfish in the pond is 833. Drop the next question 📸
