Problem 20E
Residences of U.S. CitizensAccording to the U.S. Census, 67.5% of the U.S. population were bom in their state of residence. In a random sample of 200 Americans, what is the probability that fewer than 125 were bom in their state of residence?
ANSWER:
Solution :
Step 1 of 1:
Our goal is:
We need to find the probability that fewer than 125.
Let n denotes the total Americans 200.
Let p denotes the United States population is 67.5% or 0.675.
We need to find q value.
q = 1-p
q = 1-0.675
q = 0.325
Hence, q=0.325.
