Question

0: 100% Assume that 500 births are randomly selected and exactly 126 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 126 girls out of 500 randomly selected births is unlikely. O A. It is unlikely because there are many other possible outcomes that have similar or higher probabilities O B. It is not unlikely because 126 is about one quarter of 500. ° C. It is not unlikely because girls are slightly less common than boys. O D. It is unlikely because it is not 250 as expected Determine whether exactly 126 girls out of 500 randomly selected births is unusual O A. It is unusual because girls are much more common than boys O B. It is not unusual because 126 is about the number of girls expected O C. It is not unusual because 126 girls out of 500 births is the only possible outcome. O D. It is unusual because it is not about 250 as expected Click to select your answer

Explanation / Answer

Solution:-

probability of 126 girls to be born out of 500 births is, P(girls)=126/500=0.252

The probability is not unlikely because, 126 girls out of 500 is about 0.5. Option D.

It is not unusual also, though 126 is less than the number of girls expected, that is 250, but it is not far from 250 too. Option B.
