16)to test whether the mean time to mix a batch of adhesive is the same for machines producedby four manufacturers, TiteBondMax obtained DATA on the time (minutes) needed to mix the materials. Test whether the machines have equal mean mixing time at α = 0.01a produced= 25//23//21//23b produces= 23//21//23//24c produces= 25//25//25//21d produced= 22//23//23//22a) the pvalue 0.0001 is extreme evidence that machines are not all the sameb) insignificant evidence against h0: equal mean at pvalue 0.514 machines are considered equalc)the data provide weak evidence against h0: eqyal meas at pvalue 0.072. equality of means remain plausibled) nonee) data has strong evidence against h0: equal means a pvalue 0.013. the mixing machines are not equal
