As the number of degrees of freedom increases, the chi-square distribution becomes more symmetric and bell-shaped, resembling a normal distribution. Therefore, the chi-square distribution with 12 degrees of freedom would tend to approach a normal distribution more than the one with only 3 degrees of freedom.
