Unformatted text preview: issues: 1. Should the “after” portion of the data start immediately in 1971? Why or why not? 2. Let “before” end in 1970 (i.e., don’t count the 1970-71 transition), and “after” start in 1977. Did closing the dumps significantly increase μ ? 3. Using the before and after estimates of μ and σ 2 from the previous question, quantify the reduction in extinction risk associated with closing the dumps, using whatever measure(s) you find appropriate. Justify your choice of starting population size (should you use the same sizes for the two scenarios?), as well as your choice of risk measures. Don’t forget to take into account uncertainty in the parameter estimates....
