    Answer: D. The distribution of sample variances tends to be a normal distribution.

    Step-by-step explanation:

    The properties of the sampling distribution of the​ variance include:

    • The expected value of the sample variance is equal to the population variance.

    • The mean of the sample variances is the population variance.

    • The sample variances target the value of the population variance.

    Therefore, the option that isn’t a property of the sampling distribution of the variance will be option D “The distribution of sample variances tends to be a normal distribution”.

    We should note that the sampling distribution came came in place as a result of the central limit theorem. The sample variance gives a true representation of the variance of the population as it is an unbiased estimator.
