For this problem, carry at least four digits after the decimal in your calculations. Answers may vary slightly due to rounding. In a combined study of northern pike, cutthroat trout, rainbow trout, and lake trout, it was found that 34 out of 812 fish died when caught and released using barbless hooks on flies or lures, All hooks were removed from the fish. A USE SALT (a) Let p represent the proportion ot all pike and trout that die (I.e., p is the mortality rate) when caught and released us ng barbless books. Find a point estimate for p.
