**Q19: **

The line plot shows the number of comic books owned by a group of students. How many comic books are owned by each of exactly 4 students?

**Q20: **

An electric cable is cut into pieces of different lengths. The lengths have been plotted below to the nearest a meter.

How many times longer is the longest piece of cable than the shortest piece?

If the main cable was cut into the same number of pieces so that they all have the same length, what would the length of each piece be?

**Q21: **

The given line plot shows the lengths of different line segments measured by a student using a ruler to the nearest of an inch.

How many times greater in length is the longest line segment than the smallest one?

By how much is the longest line segment longer than the smallest one?

- A an inch
- B of an inch
- C of an inch
- D of an inch
- E of an inch

Determine the total of the lengths measured.

**Q22: **

One team member ran further than the others. How many miles did he run?

- A miles
- B miles
- C10 miles
- D11 miles
- E miles

If every team member was to run the same distance, how many miles would each person run?

**Q23: **

Which of the descriptions is correct for the distribution represented by the diagram?

- AThe distribution has a gap from 6 to 18.
- BThe distribution is symmetric.
- CThe distribution has an outlier at 10.

- C6 min
- D7 min
- E6 min

Find the time taken by the slowest student to finish the race.

- C6 min
- D7 min
- E7 min

How much faster was the quickest student compared to the slowest one?

- A1 min
- B1 min
- C2 min
- D1 min
- E1 min
