Explanation:

Step1: Sum all ages

The ages are 4, 2, 3, 2, 9, 22. Sum them: \(4 + 2 + 3 + 2 + 9 + 22 = 42\).

Step2: Count number of cousins

There are 6 cousins (Iain, Hudson, Matias, Sally, Justin, Gary).

Step3: Calculate mean

Mean = \(\frac{\text{Sum of ages}}{\text{Number of cousins}} = \frac{42}{6} = 7\).

Answer:
