Among 100 fish caught in a certain lake, 25 were inedible as a result of chemical pollution. Construct (an approximate) 95% confidence interval for the true proportion of inedible fish. Round the lower and the upper bound of the interval to 3 decimal places. Hint: recall that the variance of the sample proportion is var[p] = p(1- Also, you may want to use one of the following: qnorm(0.95, lower.tail-FALSE) = -1.644854 qnorm(0.05, lower.tail-FALSE) 1.644854 qnorm(0.025, lower. tail-FALSE) = 1.959964 O (0.179, 0.321) O (0.247, 0.253) O (0.165, 0.335) O (0.246, 0.254)
