A distribution is approximately normal with a mean of 18 and a standard deviation of 4. Match the interval with the approximate percentage of data that falls within that interval.

Draggable item		Corresponding Item
Between 10 and 26		2.5%
Between 18 and 22		13.5%
Between 6 and 30		16%
Between 10 and 14		34%
Less than 10		47.5%
Between 14 and 22		68%
Between 10 and 18		95%
Greater than 22		99.7%
