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.
The value 1670 is: (Check all that apply.)

A. a parameter
B. a statistic
C. a point estimate
D. a confidence interval
E. an interval estimate

The value of 1670 is a b.) statistic as it represents a value of the sample.

Step-by-step explanation:

Since destructive testing is done it automatically means we are dealing with a sample and not a population. We cannot do destructive testing for all the population and so we have to select a sample from the popu;lation to perform the destructive testing on.

So the value of 1670 is a statistic as it represents a value of the sample.

So the mean force of 1670 is not a parameter because a parameter will belong to a population.

The mean force of 1670 is not a point estimate because a point estimate is the best guess for a parameter.

The mean force of 1670 is not a confidence interval because a confidence interval is a range between two values.

The mean force of 1670 is not an interval estimate because an interval estimate is a possible range of values for a population parameter.
