Answer
No, Megan is not correct. The median weight of her potatoes, as indicated by the box plot, is 57 grams. This means that more than half of her potatoes weigh more than 50 grams, which contradicts her statement.

Answer
When comparing the two distributions:
Megan's potatoes have a median weight of 57 grams with an interquartile range (IQR) of 20 grams. This indicates that the weights are more concentrated around the median.
Amy's potatoes, on the other hand, have a median weight of 42 grams and an IQR of 18 grams, suggesting that her potatoes are distributed in a slightly wider range compared to Megan's.
Overall, the weights of Megan's potatoes are heavier and more tightly grouped, while Amy's potatoes are slightly lighter and more variable.
