suppose a manager of yalelo is observing the fish pond to determine when it will be ready for sale. let x represent the length of a single bream taken at random from the pond. the manager concludes that x has a normal distribution with mean of 10.2 millimeters and standard deviation of 1.4 milimeters.

a. what is the probability that a single bream taken at random from the pond is between 8 and 12 millimeters long?

b. what is the probability that the mean length of five breams taken at random is between 8 and 12 millimeters?

c. looking at the results of part(a) and (b , we see that the probabilities are different. why is this the case?

Researchers used a standard fish seine to sample the fish population of Mason Pond. Most of these fish were bluegill (Lepomis macrochirus). Researchers removed fish from the seine and measured these fish on a fish board the boat. Researchers measured each fish to the nearest millimeter. Then, researchers measured all of the fish brought in by your seine, except for fish less than 15 mm. Size Category Observed Expected 15-35 mm 22 7.33 >35-55 mm 16 5.33 >55 mm...

Harvesting Fish. A fish farmer has 5000 catfish in a pond. The number of catfish increases by 8% per month and the farmer harvests 420 catfish per month. a) (4 points) Find a recursive equation for the catfish population Pn for each month. b) (4 points) Solve the recursive equation to find an explicit equation for the catfish population. c) (3 points) How many catfish are in the pond after six months? d) (3 points) Is harvesting 420 catfish per...

Assume there is a certain population of fish in a pond whose growth is described by the logistic equation. It is estimated that the carrying capacity for the pond is 1000 fish. Absent constraints, the population would grow by 240% per year. If the starting population is given by p 0 = 600 , then after one breeding season the population of the pond is given by p 1 = After two breeding seasons the population of the pond is...

Two fishermen - McKenna (M) and Natasha (N) - fish in the Paradise Pond. They make their decisions simultaneously. The amount of fish, y, that each will catch (yMand yN) depends on the amount of time, e, that each puts in each day (eM and eN) and on the amount of time that the other spends fishing each day. Each player therefore has a production function for fish: McKenna: y^M(e^M,e^N)=10e^M−1/2(e^M∗e^N) Natasha: y^N(e^M,e^N)=10e^N−1/2(e^M∗e^N) Additionally, each player derives utility from the amount...

A large pond contains f fish, of which t have been tagged. Biologist A takes a simple random sample of nA fish from the pond. Biologist B takes a simple random sample of nB fish from the fish that remain in the pond after Biologist A has drawn her sample. You can assume that nA+nB<t. a) Fill in the blank with a math expression involving any or all of f, t, nA, and nB. Explain your answer. The number of...

Suppose a team of biologists has been studying the Bethany Pond (children’s fishing pond). Let X represents the length of a single fish taken at random from the pond. This group of biologists has determined that X has a normal distribution with mean μ = 8.3 inches and standard deviation σ = 2.1 inches. What is the probability that the mean length X ̅ of five fish taken at random is between 7.3 and 10.3 inches, i.e, P (7.3 ≤...

A fish hatchery manager estimates that on average fisherpersons catch 3.5 fish each fishing trip. A random sample of 10 fisherpersons showed they caught 3.9 fish per trip, with a standard deviation of 1.7 fish. Perform a test of hypothesis at a .10 alpha level to determine whether or not her claim is true. Use a two tailed test of hypothesis
