Answer #1

null hypothesis:Hou Alternate Hypothesis:Hau 420 420 for 0.01 level with left tail test, critical z= -2.326 Decision rule:rej

from above:

Decision rule:reject Ho if test statistic z< - 2.326

(please try - 2.33 if required with only 2 decimal places

and reply if further help is required on this)
