f
The standard normal distribution function is strictly increasing. Thus p>α implies
1−Φ(n​(x−μ0​))>α⟺n​(x−μ0​)<zα​.
(1)
Rearranging gives
μ0​>x−n​zα​​,so μ0​∈(x−n​zα​​,∞).​
(2)
This is the confidence-interval/test duality for the matching one-sided procedures. The strict inequalities agree with the printed open interval.
