Determine the critical region and critical values for z that would be used to test the null hypothesis at the given level of significance, as described in each of the following:
\n" ); document.write( "a. H0: µ ≤ 24 and Ha: µ >24, α = 0.01
\n" ); document.write( "Right-tail test: CV = invNorm(0.99) = 2.3263
\n" ); document.write( "-----------------------------------------------------
\n" ); document.write( "b. H0: µ =61 and Ha: µ ≠ 61, α = 0.05
\n" ); document.write( "Two-tail test: CV = +-1.96
\n" ); document.write( "-----------------------------------------------------
\n" ); document.write( "c. H0: µ ≥27 and Ha: µ <27, α = 0.10
\n" ); document.write( "Left-tail test: invNorm(0.10) = -1.2816
\n" ); document.write( "======================================================
