Question

180 people are asked how many siblings they have?
the (incomplete) results are shown below (please use 4 decimal places when apply):

of siblings frequency relative frequency cumulative frequency

0 0.2278 41
1 37 0.2056 78
2 31 0.1722 109
3 42 0.2333 151
4 29
complete the table and determine what percent of the people have exactly three sibling(s)? %
hint

Explanation:

Step1: Recall Relative Frequency Formula

Relative Frequency = $\frac{\text{Frequency}}{\text{Total Number of Observations}}$. Total is 180. For 3 siblings, relative frequency is 0.2333. To find percentage, multiply by 100.

Step2: Calculate Percentage

Percentage = $0.2333 \times 100 = 23.33\%$ (using 4 decimal places, but here we can present as is or round, but the relative frequency given is 0.2333, so multiplying by 100 gives the percentage).

Answer:

23.33%
