ANOVA

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

See data below, please.

.The data provides strong evidence against H0: Equal means at pvalue 0.013. The mixing machines are not all equal.

None of the answers are correct.

.

The data provide insignificant evidence against H0: Equal means at pvalue 0.514. The machine are considered equal.

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

The data provide weak evidence against H0: Eual means at pvalue 0.072. Equality of means remains plausible.(this is the answer I came up with-is this correct?)

The data provides strong evidence against H0: Equal means at pvalue 0.001. The mixing machines are not all equal.

Thank you!
