16 The incomplete histogram and table give information about the ages of people living in a village.

| Age (\(x\) years) | Frequency |
|---|---|
| \(0 \leqslant x \lt 10\) | 100 |
| \(10 \leqslant x \lt 15\) | 60 |
| \(15 \leqslant x \lt 30\) | |
| \(30 \leqslant x \lt 50\) | |
| \(50 \leqslant x \lt 75\) | 50 |
| \(75 \leqslant x \lt 80\) | 20 |
(i) Use the histogram to complete the table.
(ii) Use the table to complete the histogram.
(4)
| Scheme | Marks |
|---|---|
| (i) 120 ,100 | M1 |
| A1 | |
| (ii) Blocks at 5, 1, 2 squares | B1B1 |
| (Total 4 marks) |
Notes
M1: 1 square = 10 people
or any correct fd value seen in correct place with no errors
A1: both values correct
B1B1: for all 3 correct blocks, B1B0 for 1 or 2 correct blocks.
Apart from questions 5b, 8, 15d, 20b, 21b, 23, 24b (where the mark scheme states otherwise) the correct answer, unless clearly obtained by an incorrect method, should be taken to imply correct working.
