Question

a group of 12 randomly selected students were asked how many traffic tickets they have received since they started driving.

number of tickets
1 1 2 0
3 4 1 1
0 0 0 0

create a dot plot of the data.

a. dot plot image

b. dot plot image

c. dot plot image

d. dot plot image

Explanation:

Step1: Count occurrences of each ticket number

  • For 0: Count the number of 0s in the data. The data is [1,1,2,0,3,4,1,1,0,0,0,0]. So, number of 0s: 4.
  • For 1: Count the number of 1s. The 1s are at positions 0,1,6,7. So, number of 1s: 4.
  • For 2: Count the number of 2s. There is 1 (at position 2).
  • For 3: Count the number of 3s. There is 1 (at position 4).
  • For 4: Count the number of 4s. There is 1 (at position 5).

Step2: Match with dot plot options

  • Option A: For 0: 4 dots, 1: 5 dots, 2:1 dot, 3:0 dots, 4:2 dots. Doesn't match.
  • Option B: For 0: 4 dots, 1: 4 dots, 2:1 dot, 3:1 dot, 4:1 dot. Matches our counts (0:4, 1:4, 2:1, 3:1, 4:1).
  • Option C: For 0:4 dots, 1:3 dots, 2:2 dots, 3:2 dots, 4:1 dot. Doesn't match.
  • Option D: For 0:2 dots, 1:4 dots, 2:3 dots, 3:2 dots, 4:1 dot. Doesn't match.

Answer:

B. (The dot plot with 4 dots at 0, 4 dots at 1, 1 dot at 2, 1 dot at 3, and 1 dot at 4)
