Confidence intervals plots

- [Voiceover] In this movie, I will show you how to create confidence interval plots using Minitab. Open your exercise file 03-03. Here we have processing time data for four office locations: A, B, C, D. I want to compare the means of these processing times across these four offices. Since we have sample data, I would like to try and rate confidence interval plots for the population mean. To do that, go up to Graph, Interval Plot, and since our data are located in four columns, so we choose Multiple Y's and because we have no groupings or subgroupings, we'll stick with Simple. Select OK. Highlight all four columns and OK. There we are, confidence interval plots for the mean at 95% confidence interval. We have the mean being the blue dots and the limits being the ends of these intervals. So to summarize, our command is Graph, Interval Plot. So that's confidence interval plots using Minitab. Thank you.
