Question
Consider a set of 20 samples from a standard normal distribution. We square each sample and sum all the squares. The number of degrees of freedom for a Chi Square distribution will be?(1 Point)402010None of these
Solution
The number of degrees of freedom for a Chi Square distribution in this case will be 20. This is because each sample from the standard normal distribution contributes one degree of freedom, and since there are 20 samples, there are 20 degrees of freedom.
