To solve this problem, let's review all of the options to see which one is true.
Option A. About a fourth of the students prefer small screens.
For this option focus on the information about the students:
The total of students surveyed was 100, a fourth of 100 is :
[tex]\frac{100}{4}=25[/tex]
If this option were true, about 25 students would have preferred small screens. This is not true since 48 (almost half of the students) preferred small screens.
Option B. Most of the people surveyed were adults.
As we can see from the table:
The total of students surveyed was 100 and the number of adults surveyed was also 100, thus this option is not true because not most of the people surveyed were adults --> Adults and students were surveyed equally.
Option C. Most of the adults prefer a large screen size.
In this options, let's focus on the information about the adults:
82 out of 100 adults prefer a large screen size, thus it is true that most of the adults prefer a large screen size. This is the correct option.
Option D. Most of the people surveyed prefer a small screen size.
As we can see from the table:
Out of a total of 200 people surveyed, 66 prefer a small screen size and 134 prefer a large screen size
--> most of the people who prefer a large screen size rather than a small one, this option is not true.
Answer: C. Most of the adults surveyed prefer a large screen size.
