Refer to Exercise $3.86 .$ The maximum likelihood estimator for $p$ is $1 / Y$ (note that $Y$ is the geometric random variable, not a particular value of it). Derive $E(1 / Y) .[\text { Hint: If }|r|<1$, $\left.\sum_{i=1}^{\infty} r^{i} / i=-\ln (1-r) .\right]$.

Intuitively, p-value is the probability that if the null hypothesis is true, we get = an outome at least as extreme as the observed one_Consider this example: Suppose that we flip coin 6 times and we get heads all six times: Our null hypothesis is that the coin is fair.
