T07-00 - 1 T07-00 1 Population Sampling Distribution Purpose Allows the analyst to determine the mean and standard deviation of a sampling distribution for population scenario's involving means and proportions. The template also calculates the plus and minus 1, 2 and 3 standard deviation points on the sampling distribution. A graphical display of all these calculations showing the approximate normal sampling distribution is created. Inputs Mean Scenario Sample Size Population Mean & Standard Deviation Proportion Scenario Sample Size Population proportion Outputs Sampling Distribution Statistics Mean & Standard Error mean – 3sd, mean – 2sd, mean – 1sd, mean + 1sd, mean +2sd, mean + 3sd Graph of Sampling Distribution

2
T07-00 - 2 Mean Scenario: Input the mean, standard deviation, & sample size Sampling Distribution statistics and graph are automatically calculated

3
T07-00 - 3 Proportion Scenario: Input the mean, standard deviation, & sample size Sampling Distribution statistics and graph are automatically calculated

4
T07-00 - 4 Mean Scenario: Example Calculate the sampling distribution mean and standard error for a sample of size 30 drawn from a population with the following parameters population mean of 51,800 population standard deviation of 4000 Draw a graph of the sampling distribution showing the sampling distribution mean plus and minus 1, 2 and 3 standard deviations.
