The answers are a) .1129 b) .5725 and c) .1124. Please explain how to solve the problem step by step.
Homework Answers
a) P(exactly 7 tagged fish) = 100C7 * 300C13/400C20 = 0.1129
b) P(tagged fish between 4 and 6) = 100C4 * 300C16/400C20 + 100C5 * 300C15/400C20 + 100C6 * 300C14/400C20 = 0.5725
c) n = 20
p = 100/400 = 0.25
P(X = x) = nCx * px * (1 - p)n - x
P(X = 7) = 20C7 * (0.25)^7 * (0.75)^13 = 0.1124

Problem 6 A lake contains 600 fish, eighty (80) of which have been tagged by scientists. A researcher randomly catches 15 fish from the lake. a. Find a formula for the probability mass function of X, the number of fish in the researcher's sample, which are tagged b. Find the probability that none of the fish he catches are tagged c. What is the number of tagged fish he expects to catch?

BINOMIAL DISTRIBUTIONS 2. It is believed that 62% of all adult Americans listen to National Public Radio (NPR) on a regular basis. Assume that adult Americans make their decisions independently of each other. We randomly select 15 adult Americans and let X = the number who listen to NPR on a regular basis. (a) X is Binomially distributed because there are a fixed number of trials, n- (each trial...

Reconsider problem 1 but suppose that the sample is selected with replacement. A small pond contains 30 fish, 10 of which have been tagged. Suppose that a fisherman’s catches four fish by catching a fish, noting whether it is tagged, releasing it, and repeating until four fish have been caught. (Assume that these four fish form a random sample of size four selected with replacement.) Let X denote the number of tagged fish that are caught. a) What is the...
