Problem 94SE
A random sample of nine pairs of observations is recorded on two variables x and y . The data are shown in the following table and saved in the LM7_119 file. Do the data provide sufficient evidence to indicate that the probability distribution for x is shifted to the right of that for y? Test, using α = .05.
