    How can I make confidence intervals for these values?

      Hi, I'm new to Tableau and also just started learning statistics this past week, so forgive me if I'm bad at explaining!

       

      I was able to find the confidence interval for some of my other data sheets, but I've been struggling with this one.  I don't know what I need to find the standard deviation of to fill in this formula 1.96 * ( STDEV([% Of Correct Decisions]) / SQRT(COUNT( [% Of Correct Decisions] ))  ).  I did that but that was obviously wrong.
