Give the z notation, z(0.xxxx), for the following z-scores.
1.91= First I used the table to get .4719, which isn't right. Then I added .5 to get .9719, which isn't right, so is it .5-.4719= .0281?
-.75= Would this be .5+.2734= .7734?
1.06= .5-.3554= .1446?
-2.32= .5+.4898= .9898?
Do I add .5 to the z-score for negative numbers and subtract the z-score from .5 for positive values? I think this would be right because the portion I shaded on a sketch is different for positive and negative numbers.
Thanks! I also updated a few of the threads with the parts of the problems I was still struggling with. Thanks!
