      If p-value is less than 0.05, H0 is rejected, so gender matters. We need to keep the dummy and interaction term in (16). That means, running two separate regressions, one for female and one for male, is better idea. ii. If p-value is greater than 0.05, H0 is not rejected, so gender does not matter.

      Since our p-value of 0.3472 is greater than 0.05, we fail to reject H0 and state that: The IQ of superb drug patients (M = 97.65) is not signi cantly di erent than 100, z=-0.94, p = 0.3472. To do this in R, we need to be sure to double our p-value since this is a two-tailed test. Here’s how to calculate the p-value in one step.

For example if the p-value = 0.08, then we would fail to reject H 0 at the significance level of α=0.05 since 0.08 > 0.05, but we would reject H 0
