- A random sample is obtained from a normal population with unknown mean μ, but with known variance.
We test the hypothesis H0: μ=μ0 and compute a 95% confidence interval for μ based on the sample.The diagram below represents the null-hypothesis value μ0 and the 95% confidence interval based on x.bar.
For a test of H0 (against a two-sided alternative), the p-value is closest to
