question 51

Essay

A trout hatchery had more 4 year-old fish than they could use one year, so they held about 1000 of them over until the next year. The hatchery routinely moved fish from one pond to the next each year and 10,000 three-year old fish were placed in the pond with the leftover four-year old fish. When the fish were finally taken out of the pond for releasing into streams, what would the distribution of the weights of the released fish look like? Describe the
distribution as well as you can and draw a picture.
