Freeman Introduction to the Practice of Statistics ISBN:9781319013387 Author:David S. Moore, George P. McCabe, Bruce A. Craig Publisher:W. H. Freeman How do you find the mean of the sampling distribution of sample means?If the population is normal to begin with then the sample mean also has a normal distribution, regardless of the sample size. For samples of any size drawn from a normally distributed population, the sample mean is normally distributed, with mean μX=μ and standard deviation σX=σ/√n, where n is the sample size.
How do you find the population mean?The population mean can be calculated by the sum of all values in the given data/population divided by a total number of values in the given data/population.
What is the mean of a population if the mean of the sampling distribution of sample means is?The mean of the distribution of sample means is equal to the population mean, so 1. 8.5 and 2. 5.16. The variance of the sampling distribution of sample means is the population variance / sample size, so 3. 4.17/2 = 2.085.
When the mean of a number is 18 What is the mean of the sampling distribution?int the given question, the Mean of the number is 18 hence, the Mean of the sampling distribution is 18.
