Fishing: Barbless Hooks In a combined study of northern pike, cutthroat trout, rainbow trout, and lake trout, it was found that 26 out of 855 fish died when they were caught using barbless hooks on flies or lures and then released. All hooks were removed from the fish (Source: A National Symposium on Catch and Release Fishing, Humboldt State University Press).

(a) Let p represent the proportion of all pike and trout that die (i.e., p is the mortality rate) when they were caught using barbless hooks and then released. Find a point estimate for p.

(b) Find a 99% confidence interval for p, and give a brief explanation of the meaning of the interval.

(c) Check Requirements Is the normal approximation to the binomial justified in this problem? Explain.
