Question

Given the significance level α=0.05α=0.05 find the following
(i.e. give the zz value that marks the start of the rejection region ... if you're lower tailed, it's the zz value that has left area of 0.05; if you're right tailed, it's the zz value whose area to the right is 0.05; if you're two-tailed, it's the absolute value of the zz value that has left area of 0.05/2 ... note the divided by 2 part!!):

(a)    lower-tailed zz value
z=z= 

(b)    right-tailed zz value
z=z= 

(c)    two-tailed zz value
|z|=|z|=  (so give the positive critical value)
