Final answer:
Approximately 10% of deaf children are born into families with deaf members.
Step-by-step explanation:
In a healthy baby nursery, the average number of babies born with significant hearing loss (deafness) is approximately 2 per 1,000 babies. Therefore, in a randomly surveyed sample of 1,000 babies from healthy baby nurseries, we can expect about 2 babies to be born deaf. This means that the percentage of deaf children born into families with deaf members would be 0.2% (2 out of 1,000) which is equivalent to option A) 10%.
