Definition 6.4. A continuous random variable X is said to have a chi-square distribution with r degrees of freedom if its probability density function is of the form 1 if 0 0. If X has a chi-square distribution, then we denote it by writing X ~ x²(r). 17. If the random variable Y has a chi-square distribution with 54 degrees of freedom, then what is the approximate 84th percentile of Y?

Definition 6.4. A continuous random variable X is said to have a chi-square distribution with r degrees of freedom if its probability density function is of the form 1 if 0<x < o∞ r(5) 25 a5-1e- f(x) = otherwise, where r > 0. If X has a chi-square distribution, then we denote it by writing X ~ x²(r). 17. If the random variable Y has a chi-square distribution with 54 degrees of freedom, then what is the approximate 84h percentile of Y?
