The notation F1F1F1S1?F1F1F10 = .05 indicates a significance level of 0.05 or 5%, which refers to the proportion of the curve that makes up the rejection region in hypothesis testing. This means 5% of the distribution curve is designated for the rejection area, typically in the tails, depending on whether it's a one-tailed or two-tailed test.
