An ecologist is testing whether the acidity level (pH) of a lake has changed from its normal level of 7.0.
  • \(H_0: \mu = 7.0\).
  • \(H_1: \mu \neq 7.0\).
The test produces a \(p\)-value of \(0.08\).Explain the decision that would be made if the ecologist uses a \(10\pourcent\) significance level versus a \(5\pourcent\) significance level.
