(Fish) A biologist is studying a rare species of fish. She captures four individuals and measures their weights, which are5,8,5and6kg. (a) What is the empirical conditional probability that a fish weighs more than 7kg given that they weigh more than 6kg? (b) Plot an estimate of the pdf of the fish weight using kernel density estimation with a rectangular kernel of width 2 . (c) What is the conditional probability that a fish weighs more than 7kg given that they weigh more than 6kg according to your estimated pdf?
