A manufacturing company produces electric insulators. You define the variable of interest as the strength of the
insulators. If the insulators break when in use, a short circuit is likely. To test the strength of the insulators, you carry out
destructive testing to determine how much force is required to break the insulators. You measure force by observing
how many pounds are applied to the insulator before it breaks. The accompanying data represent the amount of force
required to break a sample of 30 insulators. Complete parts (a) through (c) below.
