Suppose that 28% of domestic adoptions are transracial, and that 84% of international adoptions are
transracial in the US. A social worker takes a SRS of 200 US adoptions, and in that sample, there are 160
domestic adoptions and 40 International adoptions. The social worker will then look at the difference
(1 - D) between the proportions of transracial adoptions in each sample,
What will be the shape of the sampling distribution of the difference in sample proportions, and why?
Choose 1 answer:
Approximately normal, because we expect 11,2 transpacial and 28.8 non-transracial domestic
adoption, and 134.4 and 25.6 international adoptions, and all of these counts are at least 10,
Approximately normal, because we expect 56 transracial and 144 non-transracial domestic
adoption, and 134.4 and 25.6 international adoptions, and all of these counts are at least 10,
Not normal, because we expect fewer than 10 non transradal international adoptions.
Not normal, because we expect fewer than 10 transracial domestic adoptions,

Answer: C

Not normal, because we expect fewer than 10 non-transracial international adoptions.

Step-by-step explanation: Khan Answer

1 - .84 = .16 So an estimated 16% of international adoptions will be non-transracial. In a sample size of 40 international adoptions only 6.4 will be non-transracial because .16 * 40 = 6.4 and 6.4 is less than 10, so we can not assume normality.
