A confidence interval estimate is desired for the gain in a circuit on a semiconductor device. Assume that gain is normally distributed with standard deviation s = 25. (a) Find a 95% CI for m when n = 10 and x = 1000. (b) Find a 95% CI for m when n = 25 and x = 1000. (c) Find a 99% CI for m when n = 10 and x = 1000. (d) Find a 99% CI for m...

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. Open it and click the “Statistics” tab just above the graph. For a confidence interval for a population mean, with unknown σ, 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...
