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