. difference between the value of the sample mean and the value of the population mean.
#option c is correct
QUESTION 10 The sampling error is the a standard deviation multiplied by the sample size. b. same as the standard...
A random sample of size 36 is to be selected from a population that has a mean μ = 50 and a standard deviation σ of 10. * a. This sample of 36 has a mean value of , which belongs to a sampling distribution. Find the shape of this sampling distribution. * b. Find the mean of this sampling distribution. * c. Find the standard error of this sampling distribution. * d. What is the...
The standard deviation of the sampling distribution of the sample mean is the same as the population standard deviation according to the Central limit Theorem. (Ch8) True False
The difference between the standard error and the standard deviation is that a.The standard deviation of the population bThe standard deviation of the sample cThe standard error is the standard deviation of the sampling distribution dthe standard deviation of the sample or the population, depending on the judgment of the researcher
QUESTION 11 The starting salaries of individuals with an MBA degree are normally distributed with a mean of $90,000 and a standard deviation of $20,000. What percentage of MBA's will have starting salaries of $77,000 to $99,000? 27.99% 42.07% 30.50% 41.58% QUESTION 12 The starting salaries of individuals with an MBA degree are normally distributed with a mean of $90,000 and a standard deviation of $20,000. Suppose we randomly select 9 of these individuals with an MBA degree. What is...
A sampling distribution is constructed based on a sample size of 25. If the sampling distribution has a mean of 500 and a standard error of 15, what is the standard deviation of the original comparison population? A. 60 B. 75 C. 30 D. 50
If the sample mean and sample standard deviation are the same when doing a study with an unknown mean and standard deviation of the population. What effect does increasing the sample size have on The P value and the margin of error (assuming the same confidence level)? Also, what effect does increasing the sample size have on the width of the confidence interval (assuming the same confidence level)?
For confidence interval computations, if the sample size is increased, we expect the margin of error to: a. Increase b. Decrease c. stay the same The company you work for produces automotive parts for GM. A certain machine that makes a cutout in a piece of steel averages a cut size of 203.2085 mm with a standard deviation of 0.2083 mm. A random sample of 66 is taken from the population. What is the distribution of the sample mean? Approximately...
Question (1) According to the Central Limit theorem, what is the standard deviation of the sampling distribution of the sample mean? (02 marks) ► The standard deviation of the population The standard deviation of the sample ► The standard deviation of the population divided by the square root of the sample size. The standard deviation of the sample divided by the square root of the sample size.
Population A has a larger standard deviation than Population B. If samples of equal size are taken from both populations, which sample will have a smaller standard error of the mean? a. Unable to determine with provided information b. the sample from Population B c. the sample from Population A d. The samples will have the same standard error of the mean
2. In words, what is the standard error of the mean? Select all that apply. 1. The standard deviation of the scores in a population 2. The typical distance between scores and a population mean 3. The standard deviation of the distribution of sample means 4. The typical distance between sample means of a given size from a population mean 3. What is the relationship between sampling error and the standard error of the mean? 1. You compute the standard...
