Example 2-8
ANSWER:
Solution :
Step 1 of 4:
Given that the patients are randomly selected with replacement from the total for hospital 4.
Our goal is:
We need to find the minimum sample size ‘n’ such that the probability is at least 90% that at least one patient decides to LWBS.
The probability that visit to hospital 4 resulted in LWBS is
P(visit to hospital 4) =
