Melinda planted 18 tomato seeds on the same day. She then measured each plant 7 weeks later and determined that the mean stem length was 8 inches with a mean absolute deviation (MAD) of 2.4 inches. Which statement describes the meaning of the MAD in this situation? A One of the tomato plants is 2.4 inches longer than the mean of 8 inches.

B On average, the stem lengths of the tomato plants are within 2.4 inches of the mean length of 8 inches.

The stem lengths of all the tomato plants are 2.4 inches longer or shorter than the mean length of 8 inches.

All the stem lengths of the tomato plants are either exactly 8 inches or differ from the mean of 8 inches by exactly 2.4 inches.​
