Two manufacturers of sinus relief tablets, SINUS and ANTIDRIP, have made conflicting claims regarding the effectiveness of their tablets. A private testing organization was hired to evaluate the two tablets. The testing company tried SINUS on 100 sinus congestion sufferers and found the mean time to relief was 85.0 minutes with a population standard deviation of 6.0 minutes. A sample of 81 sinus congestion sufferers used ANTIDRIP. The mean time to relief was 86.2 minutes, the population standard deviation 6.8 minutes. Does the evidence suggest a difference in the amount of time required to obtain relief? Use the 0.05 significance level. Interpret it.
