Bart runs a food truck in front of a multi-story office building. He wants to know which type of sandwiches his customers prefer, grilled or plain. He randomly surveyed a few of his friends who have eaten at his food truck and recorded the results.

\begin{tabular}{|c|c|}
\hline Friends Preferring Grilled Sandwiches & Friends Preferring Plain Sandwiches \\
\hline 15 & 5 \\
\hline
\end{tabular}

In this case, the population consists of [tex]$\square$[/tex] and the sample consists of [tex]$\square$[/tex]. Based on the results, it can be concluded that [tex]$\square$[/tex]. The results would have been more accurate if Bart had surveyed [tex]$\square$[/tex].

In this case, the population consists of all customers of the food truck and the sample consists of the surveyed friends. Based on the results, it can be concluded that more friends prefer grilled sandwiches than plain sandwiches based on the surveyed friends. The results would have been more accurate if Bart had surveyed a larger and more diverse group of customers.
