The answer here would be Statistic.

Step-by-step explanation:

In Statistics, Statistic is a term which refers to the values or estimates obtained from the sample to evaluate the actual population parameters. In this instance, observe that the average lifetime of the sample of 500 batteries tested comes out to be 225 hours., which is used to estimate the actual average lifetime of all the batteries developed by the company, which is also the population of interest in the concerned study. Hence, the average lifetime of the sample of 500 batteries of 225 hours is a sample Statistic which can be tested to determine the actual average lifetime of the all the batteries produced by the company.
