Problem 16.4

A paint supplier claims that a new additive will reduce the drying time of its acrylic paint. To test this claim, 12 panels of wood were painted, one-half of each panel with paint containing the regular additive and the other half with paint containing the new additive. The drying times, in hours, were recorded as follows: Drying Time (hours) Panel New Additive Regular Additive 1 2 3 4 5 6 7 8 9 10 11 12 6.4 5.8 7.4 5.5 6.3 7.8 8.6 8.2 7.0 4.9 5.9 6.5 6.6 5.8 7.8 5.7 6.0 8.4 8.8 8.4 7.3 5.8 5.8 6.5 Use the sign test at the 0.05 level to test the null hypothesis that the new additive is no better than the regular additive in reducing the drying time of this kind of paint.
