Answer:
Country A because it has a smaller interquartile range
Step-by-step explanation:
A smaller interquartile range connotes that the data in the distribution do not vary much, while a larger interquartile range would suggest the data vary much.
Therefore, the island that would have an average speed close to its median would be the island whose interquartile range is smaller.
Thus, Country A has a smaller interquartile range, so therefore, it would have a daily wind speed close to its median.
