H0: µ = 30,000
\n" ); document.write( "H1: µ > 30,000
\n" ); document.write( "α = 0.2
\n" ); document.write( "C.V = Z1- α = Z1-0.2 = Z0.8 = 0.84 (table value)
\n" ); document.write( "Z =((( Ῡ-µ))⁄√n)/σ
\n" ); document.write( "Decision rule: Reject H0 if /Zcal/ is greater than /Ztab/, otherwise do not reject.
\n" ); document.write( "Ῡ = 32,000
\n" ); document.write( "σ = 3,500
\n" ); document.write( "µ = 30,000
\n" ); document.write( "n = 16
\n" ); document.write( "Zcal =((( Ῡ-µ))⁄√n)/σ
\n" ); document.write( "Zcal =(((32000-30000))⁄√16)/3500
\n" ); document.write( "Zcal =(((32000-30000))⁄√16)/3500
\n" ); document.write( "Zcal =(((2000))⁄4)/3500
\n" ); document.write( "Zcal =500/3500
\n" ); document.write( "Zcal = 0.143 Ztab = 0.84
\n" ); document.write( "Decision: since Ztab > Zcal we retained H0 and conclude that the budgeted amount is 30,000 at 80% level of significance.
