Given information
Given that, the average length of a maternity stay in a U.S. hospital is said to be 2.4 days with a standard deviation of 0.9 days. We randomly survey 80 women who recently bore children in a U.S. hospital.
We have to choose which is more likely among these two:
i. An individual stayed more than five days.
ii. the average stay of 80 women was more than five days.
Step-by-step explanation
The probability that an individual stayed more than 5 days in the U.S hospital is . The probability that the average stay for the sample of 80 women was more than 5 days is . Clearly, the probability that an individual stayed more than 5 days in the U.S hospital is greater than the probability that the average stay for the sample of 80 women was more than 5 days. Therefore, it can be concluded that an individual who stayed more than 5 days in a U.S hospital is more likely.
