Question

1.7.9. The median and quantiles, in general, are discussed in Section 1.7.1. Find the median of each of the following distributions: (a) $p(x) = \frac{4!}{x!(4-x)!}(\frac{1}{4})^x(\frac{3}{4})^{4-x}$, $x = 0, 1, 2, 3, 4$, zero elsewhere. (b) $f(x) = 3x^2$, $0 < x < 1$, zero elsewhere. (c) $f(x) = \frac{1}{\pi(1+x^2)}$, $-\infty < x < \infty$.

Step 1

** The given probability mass function (PMF) is $p(x) = \frac{4!}{x!(4-x)!}(\frac{1}{4})^x(\frac{3}{4})^{4-x}$ for $x = 0, 1, 2, 3, 4$. This is a binomial distribution $B(n, p)$ with $n=4$ and $p=\frac{1}{4}$. First, calculate the probabilities for each value of Show more…
