Evaluate a chi-squared probability density function 5 points A probability density function, or PDF, tells you how likely a sampled random variable is to occur with a certain value. For the chi squared distribution, the PDF is x2 e 2 f(x) r) 0, otherwise Compose a function f x cases for f x ) are which accepts a parameter x (a numerical value) and returns the value f(x) as defined above.
