13-17. A paint manufacturer wants to determine if its new formula for exterior house paint is superior to the old formula. Sixteen large panels of wood were selected. The panels were paired into sections, and the two paints were randomly applied, one to each section of each panel. After exposure to the elements for nine months, reflectivity readings were taken of each side of each panel. If the old formula is more reflective, an “O” is recorded;

if the new formula turns out to be brighter, an “N” is recorded:

NNNNOONNNONNNNON Is there any evidence to indicate that the new formula is superior to the old one? Use α = 0.05.
