To test whether the mean time to mix a batch of adhesive is thesame formachines produced by four manufacturers, TiteBondMax obtained DATA (attached) on the time (minutes) needed to mix the materials. Test whether the machines have equal mean mixing time at ax= 0 .01 .

A The data provide insignificant evidence against HO: Equal means at pvalue

0.514. The machine are considered equal.

B None of the answers are correct.

C The data provide weak evidence against HO: Equal means at pvalue 0.072. Equality of means remains plausible.

D The data provide strong evidence against HO: Equal means at pvalue 0.013. The mixing machines are not all equal.

E The data provide extreme evidence against HO: Equal means at pvalue 0.001. The mixing machines are not all equal.

F The pvalue 0.0001 is extreme evidence that the machines are not all the same.
