Question

Assume that 1200 births are randomly selected and exactly 595 of the births are girls. Use subjective judgment to determine whether the given outcome is unlikely, and also determine whether it is unusual in the sense that the result is far from what is typically expected. Determine whether exactly 595 girls out of 1200 randomly selected births is unlikely.

A. It is not unlikely because girls are slightly less common than boys.
B- t is unlikely because it is not 600 as expected.
C. It is unlikely because the probability of this particular outcome is very small, considering all of the other possible outcomes.
D. It is not unlikely because 595 is about half of 1200.

Determine whether exactly 595 girls out of 1200 randomly selected births is unusual.
A. It is unusual because girls are more common than boys.
B. It is unusual because it is not 600 as expected.
C. It is not unusual because 595 girls out of 1200 births is the only possible outcome.
D. It is not unusual because 595 is about the number of girls expected.

Answer 1

Lets assume that 1200 births are randomly selected and exactly 595 of the births are girls.

In percentage this is :
`(595)/(1200)*100=49.58\%`

This is approx 50%. We can say that almost random 50% are girls.

So, It is unlikely because the probability of this particular outcome is very​ small, considering all of the other possible outcomes.

Part B: It is not unusual because 595 is about the number of girls expected.
