Given the bar graph that shows the percentage of adults that use the internet for specific tasks, you can identify that these are:
[tex]E-mail=34\text{\%}[/tex][tex]Information\text{ }Searches=29\text{\%}[/tex][tex]News=25\text{\%}[/tex][tex]Job=18\text{\%}[/tex][tex]School=13\text{\%}[/tex]
By definition, the Roster Method is used to list the elements of a set in a row inside curly brackets.
In this case, you know that "x" is a task in which usage lies between 15% and 33%. Therefore, you have to list all the tasks whose percentages are between 15% and 33%:
[tex]\lbrace Information\text{ }Searches,News,Jobs\rbrace[/tex]
Hence, the answer is: First option.
