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. You collect the force data for 30 insulators selected for the experiment and find out that the mean force is 1670. Based on that, you construct an interval from 1570 to 1770 and claim that this interval can be one of the 95% intervals around the sample means that contain the population mean force. This interval is Check all that apply. a statistic a parameter an interval estimate a point estimate a confidence interval
