I am trying to find the percentage of people with a higher IQ then 111.
I have the equation, P(y>111) = P(z >.69)
At this point I believe I subtract 1 from a decimal number but I don't know what decimal number. It may come from a chart, but I guess I am not familiar with using the chart. After I do the subtraction I can find the percentage. Can anyone show me how to finish my problem?
