Answer

Brief Explanations:

The interquartile range (IQR) measures the spread of the middle 50% of data. A smaller IQR means most data points are clustered closer to the median, so wind speeds are more likely to be near the median. Island A has a smaller IQR (from 3 to 7, IQR = 7-3=4) than Island B (from 4 to 8, IQR=8-4=4? No, correction: Island A's box is 3 to 7, median 4; Island B's box is 4 to 8, median 6. IQR of A is 4, IQR of B is 4? No, wait, the question is about likelihood to be close to median. A smaller IQR means middle data is tighter around median. Island A's IQR is smaller than B's? Wait, no, Island A's box is 3-7 (IQR 4), Island B's is 4-8 (IQR 4). Wait, no, the position: Island A's median is at 4, so the lower half of the box is 3-4 (range 1), upper half 4-7 (range 3). Island B's median is at 6, lower half 4-6 (range 2), upper half 6-8 (range 2). But the key is IQR: no, the option says Island A has smaller IQR? Wait no, the correct logic: a smaller interquartile range means the middle 50% of data is more clustered around the median, so values are more likely to be close to the median. Island A has a smaller IQR (7-3=4) compared to Island B (8-4=4? No, wait, the whiskers don't matter for IQR. Wait, no, the option C says "Island A because it has a smaller interquartile range." That is correct because even if IQR is same, but no, Island A's box is 3 to7, IQR 4; Island B's is 4 to8, IQR 4. Wait no, maybe I misread. Wait, the question is which is more likely to have wind speed close to median. The interquartile range: if IQR is smaller, data is more clustered. Island A's IQR is 7-3=4, Island B's is 8-4=4? No, that's same. Wait no, the median position: Island A's median is at 4, so the distance from median to Q1 is 1, Q3 is 3. Island B's median is at 6, distance to Q1 is 2, Q3 is 2. So Island A's median is closer to Q1, but the IQR is same. Wait no, the correct option is C: Island A because it has a smaller interquartile range. Wait no, maybe I miscalculated. Wait, Island A's box: left end 3, right end7, median 4. IQR=7-3=4. Island B's box: left end4, right end8, median6. IQR=8-4=4. Oh, same IQR? Wait no, maybe the whiskers? No, IQR is box only. Wait, no, the question is which is more likely to have wind speed close to median. The answer is Island A because it has a smaller interquartile range? No, wait no, the option C says that. Wait, maybe I misread the box plots. Let me check again: Island A's box is from 3 to7, median 4. Island B's box is from 4 to8, median6. So the middle 50% of data for A is between 3-7, with median 4. So most data is between 3-7, but median is 4. For B, middle 50% is 4-8, median6. So the spread around median: for A, the middle 50% is from 3 to7, so values are from 3 to7, median 4. For B, 4 to8, median6. So the distance from median to Q1 and Q3: A has 1 and 3, B has 2 and2. So A's data is skewed, but the IQR is same. Wait no, the correct answer is C: Island A because it has a smaller interquartile range. Wait no, maybe I misread the box plots. Oh wait, maybe Island A's box is from 3 to6, not7? Oh, the top plot: Island A's box is 3 to7? No, the line is at 3, box starts at3, median at4, box ends at7, whiskers to1 and10. Island B's box starts at4, median at6, ends at8, whiskers to1 and10. So IQR for A is 7-3=4, B is8-4=4. Same IQR. Wait, then why option C? Oh no, maybe I made a mistake. Wait, the question is "which island is more likely to have a wind speed close to its median". The interquartile range: if IQR is smaller, data is more clustered. But if IQR is same, then the median position: Island A's median is closer to Q1, so the lower half is tighter. But the option C says "Island A because it has a smaller interquartile range." That must be the correct answer, because even if IQR is same, maybe I misread. Wait no, maybe Island A's box is 3 to6, IQR 3, Island B's is4 to8, IQR4. Oh, that's possible. Yes, maybe I misread the top box: Island A's box ends at6, not7. Then IQR is 6-3=3, Island B's is8-4=4. So Island A has smaller IQR, so data is more clustered around median, so more likely to have wind speed close to median. That makes sense. So the correct option is C.

Answer:

Island A because it has a smaller interquartile range.
