Question
Which statement about the chi-square test of population variance is most accurate?
The critical values do not vary with sample size.
It is extremely sensitive to violations of the assumption that the population is normally distributed.
The degrees of freedom is given by 2n – 1.
The value of alpha () is equal to 1 + (level of confidence expressed as a proportion).
As the df increases, the chi-square distribution becomes more sharply peaked.
