in the lecture(minute 1:24) the p value is 0.001........ then in minute 1:32, it is shown as 0.0001 is this wrong?.... then you compare it with the alpha.... but in minute 2:34 it is shown that for a two tail test, the number of the table should be multiplied by 2.... so the p-value is 0.002 ???????? thanks

I have the same question! Thank you for addressing this issue!

yes this seems wrong. Ive noticed a lot of this with this course and I'm over it. Ive spent a lot of time confused with certain things and then realizing there are mistakes. so annoying

Trust the math the P is 0.001 and still works for the demo. Annoying yes but let's move on.
