Which of the following is not a characteristic of the chi-square distribution? Select all correct answers. Select all that apply: The mean of the chi-square distribution is located to the left of the peak. The chi-square curve is nonsymmetrical. The χ2 curve approaches, but never touches, the positive horizontal axis. As the degrees of freedom increases, the chi-square curves look more and more like a normal curve.
