Question

{ In a recent basketball game, a player who makes 65% of his free throws made eight consecutive free throws. Assuming that free-throw shots are independent, determine whether this feat was unusual. }

I'm just a little lost on how to determine if it's unusual or not.

I have this so far:

.65 x .65 x .65 x .65 x .65 x .65 x .65 x .65 = .0318644813

So generally, doing this would be a 3.2% chance. Does that mean that it's unusual he did this?

Answer 1

Yes, if you are using P = .05 as level of significance. However, no, if you are using P = .01.
