To test whether the mean time to mix a batch of adhesive is the same for machines produced by four manufacturers, TiteBondMax obtained DATAon the time (minutes) needed to mix the materials. Test whether the machines have equal mean mixing time at = 0.01.

HINT: We state that the evidence against H0 is

• Extreme when p value < 0.001
• Overwhelming when 0.001 p value < 0.01
• Strong when 0.01 p value < 0.05
• Weak when 0.05 p value < 0.10
• Insignificant when 0.10 p value
