Problem 12BSC

 

In Exercises, assume that 400 births are randomly selected. 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.

Exactly 197 girls.

Step-by-Step Solution:
Step 1 of 3

Solution 12BSC

Since probability of getting exactly 197 girls in randomly selected 400 births is very low so this event is unlikely. Here births are chosen randomly so around 200 girls will be the highest probability zone but exactly 197 make it unlikely. And since the outcome 197 girls neither far above nor far below the number of girls we expect in 400 births (around 200 girls) so this outcome neither unusually high or nor unusually low. So the event of exactly 197 girls in 400 births is unlikely; neither unusually high nor unusually low.
