| chamad | I got the answer as follow: From table (1)z less than 2=0.9772 and (2)z less than 1=0.8413 The difference (1)-(2)= 0.1359 |
| mattayers | z tables are not provided on the test |
| smit0745 | how are we realistically supposed to know this? |
| hellboy18 | You will be given the Z-Table data in the test, no oone will ask you to remember any of the t,z, etc table numbers... |
| ksnider | Easy way to do this: 1 st dev has 68% 2 st dev has 95% (95-68) = 27% this is a one sided question so 27%/2 = 13.5% |
| kingirm | how did they get 0,34 and 0,47 ?? chamad gave the correct numbers. |
