Miguel conducts a survey of 750 college students to see how many of them have a part-time job. His results show that 500 of the
750 students have a part-time job. Kureshi also does a survey of college students to see how many of them have a part-time job. His results are NOT proportional to Miguel's. Which could represent Kureshi's Data? A) 200 out of 300 students surveyed have a part time job
B) 700 out of 1100 students surveyed have a part time job
C) 800 out of 1200 students surveyed have a part time job
D) 9000 out of 1300 students surveyed have a part time job
Miguel: 500 out of 750 students have part time jobs.
500 ÷ 250 = 2 750 ÷ 250 = 3
500:750 = 2:3
A) 200 out of 300 ⇒ 200/100 and 300/100 ⇒ 2:3 B) 700 out of 1100 ⇒ 700/100 and 1100/100 ⇒ 7:11 C) 800 out of 1200 ⇒ 800/400 and 1200/400 ⇒ 2:3 D) 9000 out of 1300 ⇒ 9000/100 and 1300/100 ⇒ 90:13
Among the choices, Choice B could represent Kureshi's Data because it is not proportional to the data of Miguel.
Choice D is not possible. You cannot have a result that is way beyond the scope of your population. It is impossible to get 9000 students out of only 1300 students.
