Suppose we take repeated random samples of size 20 froma population with a mean of 60 and a standard deviation of8. Which of the following statements is true about the sampling distribution of thesample mean (x)? Check all that apply.A. The distribution is normal regardless of the shape of the populationdistribution, because the sample size is large enough.B. The distribution will be normal as long as the population distribution isnormal.C. The distribution's mean is the same as the population mean 60.D. The distribution's standard deviation is larger than the populationstandard deviation of 8.

We have given information, The random sample size is n=20, The population mean μ=60. The standard…

Direction: Solve the given problems completely and correctly. 1. A population consists of the three numbers 1, 2, and 4. List all the possible samples of size n =2 whicE can be drawn with replacement from the population. Find the following: a Population mean b. Population variance C. Population standard deviation. d. Mean of the sampling distribution of sample means e. Variance of the sampling distribution of sample means f Standard deviation of the sampling distribution of sample means
Recent studies have shown that about 16% of American adults fit the medical definition of being obese. A large medical clinic would like to estimate what percentage of their patients are obese, so they take a random sample of 400 patients and find that 52 are obese. Suppose that in truth, the same percentage holds for the patients of the medical clinic as for the general population, 16%. Find the mean of the sampling distribution of p̂.
The finite population correction is most useful for which of the following? a. It adjusts the estimated mean when the sample size is a large fraction of the population size. b. It adjusts the standard error of the mean when the sample size is a small fraction of the population size. c. It adjusts the estimated mean when the sample size is a small fraction of the population size. d. It adjusts the standard error of the mean when the sample size is a large fraction of the population size.
Please state if the statement is correct or wrong and explain why. Statement 1. The sampling distribution of the sample mean with a sample size of 12 has a smaller standard error than that of the sampling distribution of the sample mean with a sample size of 13. Statement 2. Degrees of Freedom is one of the parameters of the normal distribution. Statement 3. A parameter is a function of a sample.
For normal population, the sample mean M = 35 has the same absolute value of the Z – score as a sample mean M = 43. The two samples have the same sample size in. What is the population mean?
