Explanation:

Part b

An outlier is a data point that is significantly different from other data points. By analyzing the scatter plot (even with partial info) and the coordinates:

• (12,4): Likely an outlier if most other points have higher or different attendance.
• (9,21): If other points don't cluster around this, it's an outlier.
• (6,42): Significantly higher than others, so outlier.
• (3,15), (10,21), (3,6) don't fit the outlier pattern as well as the selected ones.

• Option A: June (month 6) having different school out times could increase attendance (matches (6,42) outlier).
• Option B: December (month 12) closing for holidays could lower attendance (matches (12,4) outlier).
• Option D: November (month 11, but (9,21) is month 9; maybe typo or related to low attendance in Nov/Dec, but D says Nov close, which could affect. Wait, re - evaluate:
• A: June (month 6) busy due to school out times – causes high attendance (outlier (6,42)).
• B: December (month 12) close for holidays – causes low attendance (outlier (12,4)).
• D: November (month 11, but (9,21) is month 9; maybe error, but if museum closes in Nov, could affect Oct - Dec. However, more accurately:
• A: June (month 6) – high attendance outlier.
• B: December (month 12) – low attendance outlier.
• D: November (month 11) – if closing, could lead to low attendance around that time, but (9,21) is high. Wait, maybe initial analysis:
• A: June busy (school out times) → high attendance (6,42) is outlier.
• B: December close for holidays → low attendance (12,4) is outlier.
• D: November close for holidays → could lead to low attendance in Nov/Dec, but (9,21) is high. Maybe the correct ones are A, B, D? Wait, no, let's re - check:
• A: June (month 6) – (6,42) is high, so A is valid.
• B: December (month 12) – (12,4) is low, so B is valid.
• D: November (month 11) – if museum closes in Nov, attendance in Nov/Dec could be low, so D is valid? Wait, the outlier (9,21) is high. Maybe I made a mistake. Let's re - examine the options:
• A: June (month 6) busy because children in different states may get out of school at different times in June. This can cause a high attendance (like (6,42)), so A is correct.
• B: The museum might close for holidays in December. This can cause low attendance (like (12,4)), so B is correct.
• D: The museum might close for holidays in November. If it closes in November, attendance in October - December could be affected, maybe leading to low attendance around that time, which could be related to the low outlier (12,4) or other low points.
• Wait, but the options:
• A: Correct (causes high in June).
• B: Correct (causes low in Dec).
• D: Correct (causes low in Nov/Dec).
• Wait, but initial options:
• A, B, D are the most appropriate. But let's check again:
• A: June (month 6) – high attendance outlier (6,42).
• B: December (month 12) – low attendance outlier (12,4).
• D: November (month 11) – if museum closes in Nov, attendance in Nov/Dec could be low, so D is correct.

Answer:

A. (12,4), C. (9,21), E. (6,42)
