Question 1101868: In a combined study of northern pike, cutthroat trout, rainbow trout, and lake trout, it was found that 32 out of 800 fish died when caught and released using barbless hooks on flies or lures. All hooks were removed from the fish.
(a) Let p represent the proportion of all pike and trout that die (i.e., p is the mortality rate) when caught and released using barbless hooks. Find a point estimate for p. (Round your answer to four decimal places.)

(b) Find a 99% confidence interval for p. (Round your answers to three decimal places.)

point estimate is 32/800=0.04
99% CI half interval is z*sqrt(p*(1-p))/n=2.576* sqrt (.0384/800)=0.0178. Add and subtract that to/from 0.04 for the interval.
