A school district administered a survey to all students enrolled in their district regarding a proposed uniform policy. The results are shown in the two-way relative frequency table below.
Uniform Policy
For Against Undecided Total
Elementary School Students 0.08 0.08 0.08 0.24
Middle School Students 0.13 0.11 0.19 0.43
High School Students 0.15 0.1 0.08 0.33
Total 0.36 0.29 0.35 1
The school district wants to assure that there is positive student support for the uniform policy. In order to do this, the district wants to concentrate on promoting the policy to the largest percentage of undecided students. What student group should the district target?
A.
The district should target middle school students.
B.
The district should target high school students.
C.
The district should target all student groups.
D.
The district should target elementary school students.
C. The district should target all student groups. Because the largest percentage of undecided students is in the elementary school group, targeting all student groups ensures that the district can reach the maximum number of undecided students and promote the uniform policy effectively.
To determine which student group the district should target to promote the uniform policy to the largest percentage of undecided students, we need to compare the percentages of undecided students in each student group.
From the two-way relative frequency table, we can see that the percentages of undecided students are as follows:
- Elementary School Students: 0.08
- Middle School Students: 0.19
- High School Students: 0.08
Therefore, the district should target the middle school students, as they have the highest percentage of undecided students.
Therefore, the correct answer is: A. The district should target middle school students.
To determine which student group the district should target to promote the uniform policy to the largest percentage of undecided students, we need to examine the relative frequencies for the "Undecided" category in each student group.
From the given two-way relative frequency table, we can see that the percentages of undecided students are as follows:
Elementary School Students: 0.08
Middle School Students: 0.19
High School Students: 0.08
Comparing these percentages, we find that the middle school students have the largest percentage of undecided students (0.19), which is greater than the percentages for both elementary school students (0.08) and high school students (0.08).
Therefore, the district should target the middle school students to promote the uniform policy to the largest percentage of undecided students.
Hence, the correct answer is A. The district should target middle school students.
