COLIN:

HELEN:

don’t know if you agree. For example, the size of the sample, and whether it’s big enough to
make any general conclusions from. But I thought actually we did have quite a big sample.
COLIN:
We did. And our general method of observation seemed quite reliable. But we might not be
all that accurate as far as the actual numbers go.
HELEN:
Yeah,
