Find the z-values which give the following right hand tail areas. 1. area = 0.9881 (2 dp) 2. area = 0.9435 (2 dp) 3. area = 0.7412 (2 dp) 4. area = 0.1420 (2 dp) 5. area = 0.0121 (2 dp)

please help! thanks!!
In 1,2,3 z is obviously negative but to get its numerical value imagine the diagram turned over so that looking for those areas in the tables will give you that. In 4 and 5 subtract given area from 1 and look for the z related to that area.
