Chapter R, Problem 4.25RE

Largemouth bass Organizers of a fishing tournament believe that the lake holds a sizable population of largemouth bass. They assume that the weights of these fish have a model that is skewed to the right with a mean of 3.5 pounds and a standard deviation of 2.2 pounds.

  1. a) Explain why a skewed model makes sense here.
  2. b) Explain why you cannot determine the probability that a largemouth bass randomly selected (“caught”) from the lake weighs over 3 pounds.
  3. c) Each fisherman in the contest catches 5 fish each day. Can you determine the probability that someone’s catch averages over 3 pounds? Explain.
  4. d) The 12 fishermen competing each caught the limit of 5 fish. What’s the probability that the total catch of 60 fish averaged more than 3 pounds?
