The total annual yield of different vineyards is shown (tonnes of grapes per hectare). There are vineyards where state-of-the-art techniques are used to grow the grapes; and there are vineyards where cultivation is done by traditional methods. Examine whether yields are higher at vineyards where modern techniques are used.
