... combine them in some simple “2-dimensional confidence interval” for the pair ¹; ¾ 2 Note 2: Both estimates require the assumption that the data is coming from a normal distribution. This is a bit of a tall order, however it happens that applying a typical nonparametric test for normality to this dat ...

Much has been made of the concept of experimenter bias, which refers to the fact that for even the most conscientious experimenters there seems to be a tendency for the data to come out in the desired direction.

... way of rejecting the null hypothesis (that the mean is overweight). If we are following test #1, where the critical region is the right tail, we are in the acceptance region at any level lower than 8.247%, like the usual 1%, 5%, or even 8%, that is, at these levels, we cannot reject the hypothesis t ...
