In a combined study of northern pike, cutthroat trout, rainbow trout, and lake trout, it was found that 22 out of 845 fish died when caught and released using barbless hooks on flies or lures. All hooks were removed from the fish.
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. (Use 4 decimal places.)
Find a 90% confidence interval for p. (Use 4 decimal places.)
