Consider the stage structured diagram and its matrix representation shown above. Suppose you conduct a census of the first stage class at the end of the current year, and observe that 314 individuals have survived and will grow to enter the second stage class next year. You have also estimated the parameters shown in the matrix and they are a12 = 0.3, a21 = 0.8, a22 = 0.3, a32 = 0.3 and a33 = 0.4. Estimate how many individuals were in the reproductive stage class that produced the 314 individuals you have observed. Keep in mind these reproductive individuals also produced some individual in the first stage class who you did not observe, because they did not survive and will not progress second stage class next year. Please round your answer to the nearest whole individual. The margin of error for the correct answer is +/- 1
