A manufacturing company produces electric insulators. If the insulators break when in use, a short circuit is likely to occur. To test the strength of the insulators, destructive testing is carried out to determine how much force is required to break the insulators. Force is measured by observing how many pounds must be applied to an insulator before it breaks. The accompanying data are collected from a sample of 30 insulators.
Compute the mean, median, range, and standard deviation for the force needed to break the insulators.
