Question

the upperclassmen at a high school were planning for the schools movie night. they surveyed 195 upperclassmen of which 75 were in 12th grade. the survey also found that 81 students in 11th grade preferred comedy and 60 students preferred horror. which of the following frequency tables summarizes the data?

Explanation:

Step1: Confirm total surveyed students

Total surveyed = 195

Step2: Calculate 11th grade total

11th grade total = $195 - 75 = 120$

Step3: Calculate 11th grade horror preference

11th grade horror = $120 - 81 = 39$

Step4: Calculate 12th grade comedy preference

12th grade comedy = $75 - (60 - 39) = 54$

Step5: Verify total comedy/horror counts

Total comedy = $81 + 54 = 135$; Total horror = $39 + 21 = 60$

Answer:

The correct frequency table is:

	Comedy	Horror	Total
12th Grade	54	21	75
Total	135	60	195
