Let's say we have a p = .022 with a one-sided test H 0: μ ≥ 0. This means our test statistic is a negative value. If we have any value for μ greater than 0, say, 0.5, the test statistic will be even farther away from the mean, thus with a lower P -value. So, if you reject with H 0: μ = 0, you would reject with H 0: μ ≥ 0. newtown bridge https://heavenly-enterprises.com
