A0.600
B0.250
C0.125
D0.480
Answer & Solution
Correct answer: C. 0.125
1. Relative frequency divides the count for one outcome by the total number of observations.
2. Here the frequency is 6 five-star ratings and the total is 48 respondents.
3. Divide: 6 / 48 = 0.125, or 12.5% of respondents.
4. So the relative frequency of five-star ratings is 0.125.
5. Option A, 0.600, reads the raw count 6 as if it were already a proportion out of 10.
