A random sample pulled 43 catfish from a large lake. They were marked and released. A second sample pulled out 88 catfish. Seventeen had been marked. Calculate the estimated population.
Answer-
Estimated catfish population in that lake is 223.
To calculate the population of moving animals, Mark- recapture technique is used. In this technique some animals are captured from a particular area, then they are marked with tags and released. After some days these animals are again captured in a random way. Among these captured animals, there are some previously marked animals. The total population is being calculated with the help of this data.
Calculation is given below:

In a large lake, a sample of size 89 three-year old walleye had a mean weight of 512 grams. Suppose from previous knowledge it is reasonable to believe that = 7E1 Suppose we wish to calculate a confidence interval for mu, the true mean weight of three-year old walleye in this lake. Suppose that it is reasonable to think of our sample as a simple random sample of these fish from this lake. a) What is the margin of error...
A simple random sample of 81 observations was taken from a large population. The sample mean and the sample standard deviation were determined to be 165 and 225 respectively. The standard error of the mean is
Suppose a simple random sample of 300 was taken from a large population. The sample had 90% successes. For a 95% confidence level, find the following, rounded to the 4th decimal place. Use your T-Table to find the margin of error. a) How many successes were there? b) - c) d) Margin of Error = Points possible: 4 This is attempt 1 of 3. Message instructor about this question Submit
a random sample of 48 fish taken from a popular fishing lake showed 15 to be yellow perch. let p represent the population proportion of yellow perch in the lake a)find a point estimate for p b)find an 85% confidence interval for p
A large tank of fish from a hatchery is being delivered to a lake. The hatchery claims that the mean length of fish in the tank is 15 inches, and the standard deviation is 4inches. A random sample of 39 fish is taken from the tank. Let x be the mean sample length of these fish. What is the probability that x is within 0.5 inch of the claimed population mean? (Round your answer to four decimal places.)
A large tank of fish from a hatchery is being delivered to a lake. The hatchery claims that the mean length of fish in the tank is 15 inches, and the standard deviation is 7 inches. A random sample of 53 fish is taken from the tank. Let x be the mean sample length of these fish. What is the probability that x is within 0.5 inch of the claimed population mean? (Round your answer to four decimal places.)
A simple random sample of 64 observations was taken from a large population. The sample mean and the standard deviation were determined to be 70 and 12 respectively. The standard error of the mean is . . . (hint: enter the answer with one decimal place)
A random sample of 150 people was taken from a very large population. About 100 of the people in the sample were female. The standard error of the proportion is?
A large tank of fish from a hatchery is being delivered to a lake. The hatchery dams that the mean length of fish in the tank is 15 inches, and the standard deviation is 3 inches. A random sample of 46 fish is taken from the tank. Let x be the mean sample length of these fish. What is the probability that is within 0.5 inch of the claimed population mean? (Round your answer to four decimal places.) Need Help?...
