When using a 0.10 level of significance in a two-tailed hypothesis test with the Z-test, the decision rule for rejecting the null hypothesis (H0: μ=12.5) is as follows: If the calculated Z-statistic falls outside the critical region defined by the critical values of -1.645 and 1.645, we reject the null hypothesis. \n" ); document.write( "
