Well okay, but I am doing the math by hand in a bar.Donald Hand Jr. was 91% at the line coming into today and went 3-8 from the line.
Can someone better at math than me tell us what the statistical probability is of that happening?
It's a binomial distribution, make-no make with p=0.91
His mean for 8 shots is np or 7.2
Variance of the binomial is np(1-p) so about 0.64
He made 3 for 8 or 0.375, difference from expected of about 0.345
Divide by variance.345/0.64.
I ain't doing the long division, but just over 5 sigma eyeballing it
Which is 1 in 3.5 million in a normal distribution.
This is a small sample binomial , so I would eyeball it as a 3 sigma normal or about
0.3%, which sounds about right.
