Exam 7: Sampling and Sampling Distributions

A population has a mean of 400 and a standard deviation of 25.A sample of 100 observations will be taken.The probability that the sample mean will be greater than 405 is

If we consider the simple random sampling process as an experiment, the sample mean is

Nonsampling error that results when the incorrect measurement of the population characteristic of interest is which of the following?

Any set of data that is too large or too complex to be handed by standard data-processing techniques and typical desktop software is called which of the following?

The probability distribution of all possible values of the sample mean is

Which of the following is an example of nonprobabilistic sampling?

A population consists of 15 items.The number of different simple random samples of size 3 that can be selected from this population is

Random samples of size 600 are taken from an infinite population whose population proportion is 0.4.The standard deviation of the sample proportions (i.e., the standard error of the proportion) is

Which of the following is the largest data set size?

Random samples of size 17 are taken from a population that has 200 elements, a mean of 36, and a standard deviation of 8.The mean and the standard deviation of the sampling distribution of the sample means are

The standard deviation of a sample of 100 elements taken from a very large population is determined to be 60.The variance of the population

Four hundred people were asked whether gun laws should be more stringent.Three hundred said "yes," and 100 said "no".The point estimate of the proportion in the population who will respond "yes" is

Consider a population of five families with the following data representing the number of pets in each family. ​ a. Determine the mean and the variance of the population. b. There are ten possible samples of size 2 (sampling without replacement).List the 10 possible samples of size 2, and determine the mean of each sample. c. Using the ten sample mean values, compute the mean and the standard deviation from the mean determined.

Which of the following is NOT an example of nonsampling error?

The following data was collected from a simple random sample of a population. The point estimate of the population mean

Random samples of size 400 are taken from an infinite population whose population proportion is 0.2.The mean and standard deviation of the sample proportion are

In point estimation
