The task asks for the percentage of students who do not plan to go to graduate school, using the provided crosstabulation.
First, identify the totals relevant to the 'Graduate School' decision: the table shows a row labeled 'Yes' with 140 students and a row labeled 'No' with 260 students, across all majors (Business, Engineering, Other).
Second, compute the overall counts: total students = 400, with 140 planning to go to graduate school and 260 not planning to.
Then, calculate the requested percentage: number not planning to graduate school (260) divided by total students (400) equals 260/400 = 0.65, or 65%.
Now evaluate each answer option:
- Option 65%: This matches the computed proportion 260 out of 400, so it is correct.
- Option 52%: This would imply 0.52 of 400, which equals 208 students; this does not correspond to the 260 students not planning to go to graduate school, so it is incorrect.
- Option 32%: This implies 0.32 of 400, which equals 128 students; again, this is not the 260 who do not plan to go to graduate school, so it is incorrect.
- Option 280%: Percentages above 100% are impossible in this context since they would exceed the total number of students; this option misreads the data entirely and is incorrect.
In summary, the only option that aligns with the given counts for students not planning to go to graduate school is 65%.
