The results of the calculations are given in table 7. The figures are
point estimates with 80 per cent confidence intervals. This means that
under the assumptions given earlier we expect that the tabled intervals
will contain the true population 8 times out of 10. I have accepted the
estimates derived from fishing miles because their confidence intervals
are a bit shorter on the average.
