Question
Consider the following data from a repeated-measures design. You want to use a repeated-measures t test to test the null hypothesis Ho. Hp = 0 (the
null hypothesis states that the mean difference for the general population is zero). The data consist of five observations, each with two measurements,
A and B, taken before and after a treatment. Assume the population of the differences in these measurements are normally distributed.
