A paint supplier claims that a new additive will reduce drying time of its acrylic paint. To test this claim, 24 panels of wood were painted, 12 with paint containing the regular additive and the 12 containing the new additive. The drying times, in hours, were recorded as follows: New Regular 6.4 6.6 5.8 5.8 7.4 7.8 5.5 5.7 6.3 6.0 7.8 8.4 8.6 8.8 8.2 8.4 7.0 7.3 4.9 5.8 5.9 5.8 6.5 6.5 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. Use a = 0.05. a. State the Hypothesis Null: Alternative: b. Significant Level: c. Statistical Tool: d. Decision on Hypothesis: e.
