Collin's sampling method will better represent the entire population.
<h3>Missing part of the question</h3>
Determine which sampling method will better represent the entire population.
<h3>How to determine the better method?</h3>
From the question, we understand the Collin selected random names from the school directory.
While Karl surveyed only the students sitting close to him.
Karl's method is biased because students sitting far from him do not have a chance of being surveyed.
Hence, Collin's sampling method will better represent the entire population.

A.) First, you find the total sales. $2030 + $1540 + $1800 = $5370. Then, divide each with the total. The answer would be:
Lola: 203/537
Ahmed: 154/537
Tommy: 60/179
b.) Divide 100 by 3 for equal shares. Each person receives $33.3.
