If the survey were continued and a marine animal were encountered at a depth of 3,500 meters, it would be more likely that animal belonged to a species of whale than to a species of dolphin.: Yes
The species with the greatest number of encounters is estimated to have the highest population.: No
It is believed that not all encounters during the Mariana Islands Sea Turtle and Cetacean Survey were unique.: Yes
The table below summarizes cetacean sightings during the Mariana Islands Sea Turtle and Cetacean Survey including the total number of encounters, group-size range, depth range (m), the number of groups (n) estimation, and the mean group size (S) for n groups.
For each of the following, select Yes if the statement listed is one that can be properly inferred from the information in each of the three tabs. Otherwise, select No.

Official Solution:
The only species not encountered at a 3,500 meter depth had minimal encounters, so simply add up the encounters to see which species is more likely to be found based on the total number of encounters, to determine that more whales were encountered at nearly a 2 to 1 rate.
Sperm whale had the most encounters at 23, but its estimated size of 1-25 is well smaller than others with group size estimates in excess of 100.
This must be true since the number of encounters listed exceed the group size range for the beaked whale.
Correct answer:

The species with the greatest number of encounters is estimated to have the highest population. "No"
