Question

thirty - four high school students were surveyed and asked how many siblings they have. the dotplot below displays the distribution of responses. what percent of students have fewer than 2 siblings? 9% 24% 26% 50%

Explanation:

Step1: Count students with fewer than 2 siblings

Count dots for 0 and 1 siblings. There are 3 dots for 0 siblings and 14 dots for 1 sibling. So total is $3 + 14=17$.

Step2: Calculate the percentage

Use formula $\text{Percentage}=\frac{\text{Number of students with fewer than 2 siblings}}{\text{Total number of students}}\times100\%$. Total students is 34. So $\text{Percentage}=\frac{17}{34}\times 100\% = 50\%$.

Answer:

50%
