Assume that we have selected two independent random samples from populations having proportions p1 and p2 and that  1 = 800/1000 = 0.8 and  2 = 950/1000 = 0.95. Test H0: p1 – p2 > –.12 versus Ha: p1 – p2 < –.12 by using a p-value and by setting α equal to .10, .05, .01, and .001. How much evidence is there that p2 exceeds p1 by more than .12? (Round p-value to 4 decimal and z value to 2 decimal places. Negative amount should be indicated by a minus sign.)

 
 
  z =
 
  p - value = 
 


  Reject H0 at α =______________ , but not at α = ____________ ; ________________
