Determine if the statements below are true or false: The chi-square distribution, just like the normal distribution, has two parameters, mean and standard deviation. The chi-square distribution is always right skewed, regardless of the value of the degrees of freedom parameter. The chi-square statistic is always positive. As the degrees of freedom increases, the shape of the chi-square distribution becomes more skewed. "If you found χ2 = 10 with df = 5, you would fail to reject the Null hypothesis...
