At first this problem seems impossible!  How could a two-tailed test reject what a one-tailed test failed to reject!?!?  Answer:  if the one-tailed test shaded the wrong way!  Only z = -1.98 a sufficient value to reject a two-tailed test.  And if z = -1.98 is shaded greater than, then the one-tailed test fails to reject!  Pretty tricky!
