Question: Suppose that we are testing the null hypothesis \({{H}_{0}}:\mu =20\) versus the alternative \({{H}_{A}}:\mu \ne 20\), for a normal population with \(\sigma =6\). A random sample of nine observations are drawn from the population and we find the sample mean of these observations to be \(\bar{X}=17\). The p-value is closest to:
