Rare Events, the Sample, Decision and Conclusion · Try It 1

A normal distribution has a standard deviation of 1. We want to verify a claim that the mean is greater than 12. A sample of 36 is taken with a sample mean of 12.5.
H_0: μ ≤ 12
H_a: μ > 12
The p-value is 0.0013
Draw a graph that shows the p-value.
