1. How many students prefer Math as their favorite subject?
2. What is the marginal relative frequency of students who prefer a Visual learning style?
0.30
0.50
0.20
0.75
3. The conditional relative frequency of students who prefer Math, given that they have an Auditory learning style, is .
4. True or False: There appears to be an association between favorite subject and learning style based on the provided data.
True
False
5. A school surveyed 150 seniors about their plans after graduation: college or vocational school, and whether they plan to stay in-state or move out-of-state. 70 students plan to go to college, and of those, 40 plan to stay in-state. 30 students plan to go to vocational school and stay in-state. Complete the two-way frequency table below.
In-State
Out-of-State
College
Vocational School
Explain how you found the number of students planning to go to college and move out-of-state.
