In a population of 1,000 students, 50 were asked by random sampling what their plans were after graduation from high school. Their responses are shown in the table. A 2-column table with 4 rows. Column 1 is labeled Intention with entries College, job, military, no plans. Column 2 is labeled Number of students with entries 27, 13, 2, 8. Using proportional reasoning, make a prediction about how many students you would expect to have plans to attend college. 27 50 = x 1000 27,000 = 50x About would have plans to attend college.
