Question

3. Joseph surveyed 62 girls and 38 boys

and asked about their preferred music.
In all, 36 girls preferred country, and 7
boys preferred country. What is the
conditional relative frequency, as a
fraction, that a student's favorite music
is NOT country given that the student is
a girl?

Answer 1

The conditional relative frequency of a student's favorite music not being country given that the student is a girl is equal to:

(1 - proportion of girls who prefer country) = (1 - 36/62) = 26/62

Simplifying the fraction gives:

26/62 = 13/31

Therefore, the answer is 13/31.
