A school principal introduces a new teaching method to improve student test scores.
  • \(H_0\): The mean test score remains \(\mu = 72\) (The method has no effect).
  • \(H_1\): The mean test score is \(\mu > 72\) (The method improves scores).
The statistical test yields a \(p\)-value of \(0.041\).
State the conclusion at the \(5\pourcent\) significance level (\(\alpha = 0.05\)). Is the new method considered effective?
