To find out how many people in the sample have brown hair, we need to look at the "Hair Color" column in the data table. Here's how we can break down the information step-by-step:
1. Bob - His hair color is listed as "blonde." Therefore, Bob does not have brown hair.
2. Cathy - Her hair color is listed as "brown." So, Cathy has brown hair.
3. Samantha - Her hair color is listed as "brown." This means Samantha has brown hair.
4. Robin - Her hair color is listed as "black." Therefore, Robin does not have brown hair.
Now, let's summarize the findings: Cathy and Samantha both have brown hair. This means there are 2 people with brown hair in the sample.
Therefore, the frequency of brown-haired people in the sample is 2.
