Answer explained below
Step-by-step explanation:
Since the population was first divided into groups and the sampling was done afterwards, it was not an example of simple random sampling as it is not possible to select more than one adult from each group which would have been possible in simple random sampling.
Also, If simple random sampling is to be done, then each adult should have equal probability of being selected and should be independent of others. The 2007 adults should be selected without regard to the groups i.e 2007 adults should be chosen from the groups with no restrictions on the number chosen from each group.
