8.) A sample of 405 salmon in a hatchery are tested for a particular disease. It is found that 27 of them test positive for the disease. Round solutions to three decimal places, if necessary. The empirical probability that a randomly chosen salmon will test positive is: P(Test Positive) The empirical probability that a randomly chosen salmon will test negative is: P(Test Negative) = I 9.) Hudson buys a bag of cookies that contains 8 chocolate chip cookies, 4 peanut butter cookies, 4 sugar cookies and 8 oatmeal cookies. What is the probability that Hudson randomly selects a sugar cookie from the bag, eats it, then randomly selects a chocolate chip cookie? Round the solution to four decimal places, if necessary. P(sugar cookie first and chocolate chip cookie second)= 10.) The probability that a randomly selected Floridian is a Florida native is 0.17. The probability that a randomly selected Floridian is a registered independent voter is 0.16. The probability that a randomly selected Floridian is a Florida native and a registered independent voter is 0.07. Calculate the following probabilities. Round solutions to three decimal places, if necessary. Determine the probability that a randomly selected Floridian is a Florida native, given the person is a registered independent voter. P(Florida native | Independent Voter) = Determine the probability that a randomly selected Floridian is a registered independent voter, given the person is a Florida Native. P(Independent Voter | Florida Native) = 11.) The data from a recent test are organized by class rank and letter grade. Use this information to calculate the following probabilities. Round solutions to three decimal places, if necessary. A B C Total 15 Freshman 5 7 27 19 20 Sophomore 20 11 50 50 34 25 18 Total 77 If one student is chosen at random, Find the probability that the student was freshman. P(was freshman) = Find the probability that the student was sophomore and got a "C." P(sophomore and C) = Find the probability that the student was freshman or got an "B." P(freshman or B) = If one student is chosen at random, find the probability that the student was freshman given they got a 'A'. P(freshman | A) =
