Views Read Edit View history. It was noted that the log-transformed lead levels fitted a normal distribution well that is, the data are from a lognormal distribution. Company organization, management and quality.

Grouped data Frequency distribution Contingency table. The prediction interval only bounds a single future sample, however, whereas a tolerance interval bounds the entire population equivalently, an arbitrary sequence of future samples.

Engineering concepts Statistical intervals Statistical forecasting. A confidence interval for mu can be constructed the usual way, based on the t -distribution ; this in turn will provide a confidence interval for the median air lead level. Search all products by.

Whereas a confidence interval’s size is entirely due to sampling errorand will approach a zero-width interval at the true population parameter as sample size increases, a tolerance interval’s size is due partly to sampling error and partly to actual variance in the population, and will approach the population’s probability interval as sample size increases.

Retrieved from ” https: A prediction interval has a similar interpretation, and is meant to provide information concerning a single lead level only. Z -test normal Student’s t -test F -test.
