NOTE: The numerical values in this problem have been modified for testing purposes.
The random variable ?X is a count.
A study of the sexual health of high school students in New York state indicates that 46%46% have had sexual intercourse. ?X is the number of individuals who have ever had intercourse in an SRS of 250 high school students from New York.
Does X have a binomial distribution?
(A)No, there are no trials in this study.
(B)No, because there are more than two outcomes.
(C)Yes, because the four conditions of the binomial distribution are satisfied.
(D)No, because each individual has a different probability of having had sexual intercourse.
What are the values of n and p?
n=
p=
