Assume that population mean is to be estimated from the sample described. Use the sample results to approximate the margin of error and 95% confidence interval.
If you had 345 patients, that had an average mean of age 65 and had a standard deviation of 2.2 years. How would you calculate the margin of error of this sample? What would be the step by step process? How much would the error change if it went up to 502 patients? How could you apply this to your work situation in another area? How might you present this to another hospital or facility who may not know this?
