Q2 -Archaeology: Skull Breadths from different Epochs: samples of head breadths were obtained by measuring skulls of Egyptian males from 3 deferent epochs, and the measurements are listed below: changes in head shape over time suggest that interbreeding occurred with immigrant populations. Use a 0.05 significant level to test the claim that the different epochs do not all have the same mean. What do you conclude

Q3-Which treatment is better? A randomized controlled trial was designed to compare the effectiveness of splitting against surgery in the treatment of carpal tunnel syndrome. The results show below. They are based on evaluations made one year after the treatment. Using a 0.01 significant level, test the claim that success is independent of the type of treatment. What do the results suggest about treating carpel tunnel syndrome?
