Consider the following dependent random samples

Observations    1     2       3     4       5      6

x-values           22.0   21.0    18.1   19.6  13.2  17.5

y-values           23.1   21.7    18.7   20.7   14.7   16.4

a) Determine the difference between each set of points, xi - yi

b) Do hypothesis testing to see if µd < 0 at the α = .05.
