Answer: Sample statistics are used to make inferences about population parameters.

A statistic is a number which may be calculated from the data observed in a random sample without demanding the use of any unknown parameters.

The mean and variance of a population are population parameters.

Thus, fourth statement is the right answer "Sample statistics are used to make inferences about population parameters."
