Answer #1

Let the sample statistic be and the standard error of the sample statistic be .

Generally, the confidence interval is in the form: (Critical value * ).

To get the sample statistic, just add the lower and the upper boundary values of the confidence interval and divide the sum by 2. You will then get the sample statistic value used in creating the confidence interval.

Confidence intervals seek to estimate a population parameter with an interval of values calculated from an observed sample statistic. Demonstrate that you understand this concept by describing a situation in which one could use a sample mean or sample proportion to produce a confidence interval as an estimate of a population mean or population proportion. I am asking you to make up a situation where a confidence interval might be computed. Clearly identify the population, sample, parameter, and statistic involved...
