Determine the sample size necessary to estimate the population mean with a 96.07% confidence level and a 3.1 margin of error. Assume that the population standard deviation is known to be 9.74.
STATDISK has the ability to find the sample size required to estimate a population mean. The next question is designed to introduce you to this functions within STATDISK. The sample size determination function is located under the “analysis,” “sample size determination,” and “estimate mean” sub menu. Determine the sample size necessary to estimate the population mean with a 96.07% confidence level and a 3.1 margin of error. Assume that the population standard deviation is known to be 9.74.
