3.- 30 students are not in band.


which table shows these dates correctly entered in a two way frequency table?

Answer 1

Answer: Option 'a' is correct.

Explanation:

Since we have given that

Number of students asked in a survey = 60

Number of students who play an instrument = 35

Number of students who are in band = 30

Number of students who are not in band = 30

So, the two way frequency table would be :

Play instrument Not play instrument Total

In band 30 0 30

Not in band 5 25 30

Total 35 25 60

Hence, option 'a' is correct.
