Suppose 14% of students are veterans. From a sample of 201 students, how unusual would it be to have less than 20 veterans? Is the success-failure condition of the Central Limit Theorem satisfied? Yes. Both npnp and n(1−p)n(1-p) are ≥10≥10. No. Either np<10np<10 or n(1−p)<10n(1-p)<10. The Central Limit Theorem tells us that the distribution of sample proportions approximately follows a normal distribution with mean  and standard deviation . Given this knowledge, calculate the
