Confidence Intervals for the mean of a population when the data is numerical and the standard deviation is known; 2. Confidence Intervals for the mean of a population when the data is numerical and the standard deviation is unknown; 3. Confidence Intervals for the proportion in a population when the data is categorical. The terms used in this handout are as follows. A 99% Confidence interval... For confidence intervals, we need to shift the sampling distribution so that it is centered on the sample mean and shade the middle 95%. The shaded area shows the range of sample means that you’d obtain 95% of the time using our sample mean as the point estimate of the population mean.

**Construct a 95% two-sided confidence interval on the mean**

9. Calculating Confidence Intervals We will make some assumptions for what we might find in an experiment and find the resulting confidence interval using a normal distribution. Here we assume that the sample mean is 5, the standard deviation is 2, and the sample size is 20. In the example below we will use a 95% confidence level and wish to find the confidence interval. The commands to...
