If you are given summary statistics for a sample and want to construct a confidence interval, this can be done through the Probability Calculator in Geogebra, or Stat>Basic Stats>1-sample Z in Minitab(web). For Minitab (web), see Tutorials in D2L. For Geogebra, follow the directions below: Open it and click the "Statistics" tab just above the graph. For a confidence interval for a population mean, with unknown o, click the drop-down menu near the top (default is "Z Test of a Mean") and choose "T Estimate of a Mean." Enter the confidence level (in decimal form), sample mean, sample standard deviation, and sample size. We'll use a sample with = 65.17, s = = 3.654, n = 26. Based on this sample data, a 95% confidence interval for the population mean is: # <µ<
