Data table #1: Hair Color of Classmates (by sex) Black (Girls 3, Boys 6) Blonde (Girls 4, Boys 3) Red (Girls 2, Boys 0) Brown (Girls 5, Boys 6) Choose the BEST conclusion about the observations made above. A. The boys had 6 with black hair, 3 with blonde hair, 0 with red hair, and 6 with brown hair. B. The girls had 6 with black hair, 3 with blonde hair, 0 with red hair, and 6 with brown hair. C. More boys had blonde and red hair than girls D. Most of the girls had brown hair.
D. Most of the girls had brown hair.
To answer this question, we need to analyze the data in the table. Let's break down the information and find the best conclusion:
In the table, the hair color of classmates is given by sex. Here is the breakdown for each hair color:
Black:
- Girls: 3
- Boys: 6
Blonde:
- Girls: 4
- Boys: 3
Red:
- Girls: 2
- Boys: 0
Brown:
- Girls: 5
- Boys: 6
Now let's evaluate each conclusion:
A. The boys had 6 with black hair, 3 with blonde hair, 0 with red hair, and 6 with brown hair.
This conclusion accurately reflects the data in the table. However, it only pertains to the boys and does not consider the girls.
B. The girls had 6 with black hair, 3 with blonde hair, 0 with red hair, and 6 with brown hair.
This conclusion does not accurately represent the data in the table. It incorrectly states that the girls had 6 of each hair color, which is not the case.
C. More boys had blonde and red hair than girls.
This conclusion is incorrect. According to the table, the number of boys with blonde hair is 3, while the number of girls with blonde hair is 4. Additionally, no boys have red hair.
D. Most of the girls had brown hair.
This conclusion is accurate. According to the table, 5 girls have brown hair, while 6 boys have brown hair. Therefore, there are more girls with brown hair, making this the best conclusion.
Based on the given data in the table, the best conclusion is that most of the girls had brown hair (D).
