Researchers once surveyed college students on their Face book use. The following two-way table displays data for the sample of students who responded to the survey. How many students in the survey were in the age category of 18 to 22?
_ students.

use the app:78

do not use the app:4

both are in the 18 to 22 age category

therefore 78 + 4 is 78

82

Explanation:

78 respondents aged 18 to 22 use face book and 4 respondents aged 18 to 22 do not use face book. since there are no other options for the survey, the total number of students who were surveyed that are aged 18 to 22 would be 78 + 4 = 82.
