I have to find what separates the top 5% and the bottom 5% of the distribution. Mean is 9.75 and Standard dev is .08
I found that: -1.645= x - 9.75/ .08
I am terribly stuck as I already had found the area which was .95 looking at my chart of Positive and Negative z-scores but don't remember how to exactly find x.
I need some enlightenment, thanks so much. oH and do I have to draw the bell shaped curve as well?
