Answer:
c. neither significantly low nor significantly high.
Step-by-step explanation:
We have been given that 1700 births are randomly selected and 857 of the births are girls. We are asked to choose the correct option about number of girls using subjective judgement.
We could expect that there would be 850 boys and 850 girls on average among 1700 births.
In our given scenario there are 857 girls, so there would be 843 boys. 857 girls compared to 850 girls are close.
Now probability of choosing 857 girls or more from 1700 births is approximately 0.5041 or 50%, therefore, the outcome is neither significantly low nor significantly high.
you take each other you do multiplication and you have answer
