Ahigh school administrator determined that 22% of the students worked part-time after school with an +-8%
margin of error. if the school has 1420 students, which would represent the possible number of students that
work part-time after school?
199 to 426 students
114 to 312 students
195 to 430 students
47 to 178 students

199 to 426 students

Step-by-step explanation:

Total number of students= 1420(number of students that work part time after school hours + number of students that don't)

number of students that work part time after school hours =22% +/-8% margin error. The percentage ranges from (22-8 )= 14% to (22+8) =30℅

The possible number of students that

work part-time after school would be between

(14/100)×1420=0.14×1420=198.8 which is approximately 199 students(rounding up to the nearest whole number) and

(30/100)×1420=0.30×1420=426 students.
