Question

1. the dot plot shows the number of movies a group of students watched in the last three months: dot plot image how many total movies were watched? what conclusion can you draw from the above dot plot?

Explanation:

Part 1: Total Movies Watched

Step1: Count dots for each number

For 0: 2 dots, so \( 0 \times 2 = 0 \)
For 1: 4 dots, so \( 1 \times 4 = 4 \)
For 2: 6 dots, so \( 2 \times 6 = 12 \)
For 3: 4 dots, so \( 3 \times 4 = 12 \)
For 4: 2 dots, so \( 4 \times 2 = 8 \)
For 5: 2 dots, so \( 5 \times 2 = 10 \)

Step2: Sum all products

\( 0 + 4 + 12 + 12 + 8 + 10 = 46 \)

• The peak (most dots) is at 2 movies, so most students watched 2 movies.
• The distribution is somewhat symmetric around 2 (similar counts on either side of 2).
• Total students: \( 2 + 4 + 6 + 4 + 2 + 2 = 20 \) (matches the "20" at top left, likely number of students).

Answer:

46
