Fig. 4 shows a curve which passes through the points shown in the following table.
| \(x\) | 1 | 1.5 | 2 | 2.5 | 3 | 3.5 | 4 |
| \(y\) | 8.2 | 6.4 | 5.5 | 5.0 | 4.7 | 4.4 | 4.2 |
Use the trapezium rule with 6 strips to estimate the area of the region bounded by the curve, the lines \(x = 1\) and \(x = 4\), and the \(x\)-axis.
State, with a reason, whether the trapezium rule gives an overestimate or an underestimate of the area of this region.
