There are 520 students in the high school. A student surveys 130 randomly chosen students about their favorite ice cream flavor. The results are as follows: 29 people like strawberry, 31 people like butter pecan, 43 people like chocolate, 10 people like orange sherbet, and 17 people like vanilla.

Question

Based on the sample data approximately how many students in the school prefer vanilla?

Answer 1

To find approximately how many students in the school prefer vanilla, we can set up a proportion using the sample data.

17 students out of 130 like vanilla
x students out of 520 like vanilla

So the proportion is:
17/130 = x/520

Cross multiplying:
130x = 17 * 520
130x = 8840
x = 8840 / 130
x ≈ 68

Therefore, approximately 68 students in the school prefer vanilla.
