Question

1. which data set does the line plot represent? a 1,1,2,3,3,3,4,6,6,7,7,8,8,8 b 1,1,2,3,3,4,6,6,6,7,7,8,8,8 c 1,1,3,3,3,4,5,6,6,7,7,8,8,8 d 1,1,3,3,3,4,6,6,6,7,7,8,8,8

Explanation:

Step1: Count dots at each value

• At 1: 2 dots (so two 1s)
• At 2: 0 dots (so no 2s)
• At 3: 3 dots (so three 3s)
• At 4: 1 dot (so one 4)
• At 5: 0 dots (so no 5s)
• At 6: 3 dots (so three 6s)
• At 7: 2 dots (so two 7s)
• At 8: 3 dots (so three 8s)

Step2: Match with options

• Option A: Has a 2 (we have 0 at 2) → Eliminate.
• Option B: Has a 2 (we have 0 at 2) → Eliminate.
• Option C: Has a 5 (we have 0 at 5) → Eliminate.
• Option D: 1,1 (2 at 1), 3,3,3 (3 at 3), 4 (1 at 4), 6,6,6 (3 at 6), 7,7 (2 at 7), 8,8,8 (3 at 8) → Matches.

Answer:

D. 1, 1, 3, 3, 3, 4, 6, 6, 6, 7, 7, 8, 8, 8
