If the p-value is less than or equal to α ,we reject the null hypothesis (p ≤ α) If the p-value is greater than α ,we do not reject the null hypothesis (p > α)

Use the test statistic to determine the p-value. 4. The result is statistically significant if the p-value is less than or equal to the level of significance.
