Bergstedt et al. (2003) used the Petersen (with the Chapman modification) mark-recapture method to estimate the population size of parasitic Sea Lamprey (Petromyzon marinus) in Lake Huron. Use their results1 from “Pre” period and the 1991 parasitic feeding year in Table 3 (use the M, C, and R rows) to confirm the population estimate (in the first row of the table) and, hopefully, the confidence interval (in the second and third rows of the table). Show your work and write a formal statement about how your results compare to those in the paper.
