Q: The values in the table are measured maximum breaths of male Egyptian skulls from time periods. Changing in head shape over time suggest that interbreading occurred with immigrant populations. Use a 0.05 level significance to test the claim that the different time periods do not all have the same mean.

Do I reject the hypothesis that the means are the same: at least one of the means is different? Or accept the hypothesis that the means are all the same?
