Since majority of the parents aren't taken income consideration, the type of bias that this survey displays is the selection bias.

Based on the information given, a selection bias will occur as the Director of camp picks a random sample of parents.

In this case, the proportion of parents differs since some send their children to morning camp while others send their children to evening camps. Therefore, this can lead to a large variation in the response gotten.

Lastly, if the camp director combined the two separate samples into one, this will be a stratified sampling. This is a division of a population into smaller groups.
