Title: Two researchers are comparing a blood pressure reducing drug with a two-sided alternative ... Post by: miks on Mar 18, 2020 Two researchers are comparing a blood pressure reducing drug with a two-sided alternative hypothesis. Their test statistics show that the following z values: z1 = 1.87 and z2 = −2.45. Which one of these have the smaller p-value and why?
▸ z2 = −2.45 because the bigger z-value has a bigger area between −2.45 and 2.45. ▸ z1 = −1.87 because the area between −1.87 and 1.87 is smaller. ▸ z2 = −2.45 because the z-value indicates almost two and a half standard deviations away from the mean with the remaining areas smaller than 1.87. ▸ z1 = 1.87 value because it is closer to the mean.
