Answer:
Option: C is the correct answer.
The two-way frequency table is given as:
Band Not in Band Total
Play instrument 20 5 25
Do not play instrument 0 15 15
Total 20 20 40
Explanation:
We are given a survey of 40 students regarding whether they play an instrument or not.
We are given an information as:
1. 25 students play an instrument.
2. 20 students are in band.
3. 20 students are not in band
Hence, the table can be formed as:
Band Not in Band Total
Play instrument 20 5 25
Do not play instrument 0 15 15
Total 20 20 40
( Since, those who don't play any instruments can't even play band hence the value of that in table is 0)
