Ci half width
WebIf you are interested in a CI from a single group, then to calculate the confidence interval you need to know the sample size, sample standard deviation and the sample arithmetic average. If entering data for a CI for difference in proportions, provide the calculator the sample sizes of the two groups as well as the number or rate of events ...

Webcompute sample size given CI width (or precision) and probability of CI width. Alternatively, you can compute CI width given sample size and probability of CI width. You can also compute probability of CI width given sample size and CI width. You can display results in a table ([PSS-3] ciwidth, table) and on a graph ([PSS-3] ciwidth, graph).
WebRobert, being an intelligent industrial engineer, knows that the half width of the CI increases as the number of runs is decreased. He is therefore considering cutting the number of runs from 7 to 5 to ensure that the upper end of his CI will cover the expected mean.
