confidence interval and level of certainty

confidence interval (+/- 5% seems reasonable to me), with a reasonable level of certainty (p value less than .05 seems good)

Where do I look on Aleo's spread sheet for the +/- 5%? Does the sheet have p value? I never took stats so this is all foreign to me.

your confidence intervals between levels can't overlap.

Can someone explain what this means?

I don’t post much, so I will use this post to say Thank-You to all the members that add to this fourm. I spend a lot of time read this site everyday and it had helped my game so much.
