SOLUTION:
Step 1:
In this question, we are given the following:
Step 2:
220 people are asked how many siblings they have, and the results are shown below:
# of siblings Frequency Relative Frequency Cumulative Frequency
0 44 0. 2 44
1 55 0.25 99
2 45 0.2045 144
3 42 0.1909 186
4 34 0.1545 220
The first box is 44 because 44 is the first number on the frequency
The second is 42 because 220 - (44+55+45+34) = 42
The third box is 0.1545 because (34/220 = 0.1545)
Step 3:
What percent of the people have exactly four siblings:
![\begin{gathered} (34)/(220)\text{ x }(100)/(1) \\ =(3400)/(220) \\ =\text{ }15.45\text{ \%} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/hauz7dkenu36giyuaznvhhus1hfzc55lfx.png)
