True or False (d) The Chi-Square distribution, just like the normal distribution, has two parameters; mean and standard deviation. (e) The Chi-Square distribution is always right skewed, regardless of the value of the degrees of freedom parameter. (f) The Chi-Square statistic is always positive. (g) As the degrees of freedom increases, the shape of the Chi-Square distribution becomes more skewed. (h) If you found Chi-Square = 10 with df = 5 you would fail to reject the null hypothesis at the 5% significance level. (i) When finding the p-value of a Chi-Square test, we always shade the tail areas in both tails. (j) As the degrees of freedom increases, the variability of the Chi-Square distribution decreases.
