Female Americans Who Have Completed4Nears of CollegeThe percentage of female Americans 25 years old and older who have completed 4 years of college or more is 26.1. In a random sample of 200 American women who are at least 25. what is the probability that at most 50 have completed 4 years of college or more?
ANSWER:
Solution :
Step 1 of 1:
Our goal is:
We need to find the probability that at most 50.
Let n denotes the 200 American women who are at least 25.
Let p denotes the who have completed 4 years of college or more is 26.1%.
So, p = 1-0.261.
p = 1-0.261
p = 0.739
We need to find q value.
q = 1-p
q = 1-0.739
q = 0.261
Hence, q=0.2
