Answer

Explanation:

Step1: Read the histogram for 6 - 8 years old

The vertical axis for the bar corresponding to 6 - 8 years old is 8.

Step2: Determine the shape of the histogram

A skewed - right histogram has a longer tail on the right. Here, the tail (fewer students) is on the left (0 - 2 and 3 - 5 age groups compared to 6 - 8 and 9 - 11). So it is skewed right.

Step3: Find the peak of the histogram

The peak is the bar with the highest number of students. The bar for 9 - 11 years old has 10 students (highest).

Step4: Calculate the total number of students

Add the number of students in each age group: (1+4 + 8+10=23)

Step5: Calculate the percentage of 0 - 5 years old students

Number of 0 - 5 years old students: (1 + 4=5). Total students: 23. Percentage: (\frac{5}{23}\times100\approx21.74%)

Answer:

  1. (8)
  2. b) skewed right
  3. (9 - 11)
  4. (23)
  5. Approximately (21.74%)
