The quadratic form of the sample mean and sample variance was considered. The sample is from normal distribution. The density function of the quadratic form has been derived. The quadratic form can be applied as the test statistic for the hypothesis on expected value and variance of normal distribution. The table with approximated critical values of the test statistic has been derived.
