5. Do women and men treat female and male children differently? An observational study was conducted near the primate exhibit at the Sacramento Zoo on weekends in 1988. The data are from 37 groups of three-one adult female, one adult male, and one toddler-in which the toddler was being carried. Recorded in the table below are the gender of the adult who was carrying the toddler and the gender of the toddler Gender of toddler Gender of adult carrying child Male Female Boy Girl 17 What are the odds that an adult carrying a girl was female? A) 0.35 B) 0.50 C) 1.00 D) 2.13
Explanation / Answer
5)
odds in favour =(favourable ways)/(unfavourable ways)
Here we focus on the column of girl
Favourable ways when female carries a girl child =6
unfavourable ways when male carries a girl child =17
so odds in favour =6/17 =0.35
8)
odds in favour =2/3 =(favourable ways)/(unfavourable ways)
So that means
favourable ways =2
unfavourable ways =3
so total ways =favourable ways + unfavourable ways
=2 +3
=5
Prob =(favourable ways)/(total ways)
= 2/5
=0.4
so choice D
