B) what percent of the people have exactly one sibling ?

Answer 1

Explanation:

(A).

No' of siblings Frequency Rel. frequency Cumm. frequency

0 51 0.2429 51

1 37 0.1762 51 + 37 = 88

2 34 0.1619 122

3 41
`(41)/(169)=0.2426` 163

4 47 0.2238 210

(B).

Percent of people having exactly one sibling =
`\frac{\text{Frequency}}{\text{Total frequency}}* 100`

=
`(37)/(210)* 100`

= 17.62%
