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.
