Hi
I'm not really sure where to start for this question..
Q.
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

This is not true. Using an alpha of .05 then either a, b, or c would result in rejecting the null.Originally Posted by mmgg

Full agreement with Dason. And I couldn't see the image. And this may be HW and if this is the case you should tell us so we can help you learn and understand.
