The balancing point is 5.
The balancing point is 5.

The balancing point is 7.
The balancing point is 7.

The balancing point is 1.

Answer 1

A simple dot plot (dots = students) — each row shows the hour and the stacked dots:

3: ••••••• (7)
4: •••• (4)
5: • (1)
6: •••• (4)
7: ••••••• (7)

Mean (balancing point) = (3·7 + 4·4 + 5·1 + 6·4 + 7·7) / 23 = 115 / 23 = 5.

So the balancing point is 5.
