Another group answered question $4\mathrm{.}1,$ but this time the question presented a much higher number instead $($$$130,000)$ and people's estimates were very close to $$130,000$ and diverged significantly from the first group.

The other group also answered question $4\mathrm{.}2,$ but in their version the number presented was $5$ million, much smaller. Again, their estimates were very close to $5$ million and diverged significantly from the first group.

Given neither the secretary$\text{'}$s estimate $($knows little about the profession$/$industry$)$ nor the population number in the question has any credibility, why do you think people's estimates were very close to the given numbers and diverged significantly? Identify and explain the decision bias that explains the results in this question.
