Explanation / Answer

Ans:

For 1% significance level:

critical z value(left tailed)=-2.33

critical z value(right tailed)=+2.33

critical z value(two tailed)=-2.58 and +2.58

For 5% significance level:

critical z value(left tailed)=-1.65

critical z value(right tailed)=+1.65

critical z value(two tailed)=-1.96 and +1.96

For 10% significance level:

critical z value(left tailed)=-1.28

critical z value(right tailed)=+1.28

critical z value(two tailed)=-1.65 and +1.65
