Show how to use the chi-square distribution to calculate $P\left(a<S^{2} / \sigma^{2}<b\right)$
Added by Madison H.
Step 1
.., X_n$ be a random sample from a normal distribution with mean $\mu$ and variance $\sigma^2$. We want to find the probability $P(a < \frac{S^2}{\sigma^2} < b)$, where $S^2$ is the sample variance. Show more…
