It the p-value is less than to the alpha in <0.05). then we relect the null hypothesis, and we say the result is statistically simi If the p-value is greater than alpha (p > .05), then we fail to reject the null hypothesis, and we say that the result is statistically nonsignificant (n.s.). 3 points each.
