Determine whether you can use a normal distribution to approximate the binomial
distribution. If you can, use the normal distribution to approximate the indicated
probabilities and sketch their graphs. If you cannot, explain why and use a
binomial distribution to find the indicated probabilities. Identify any unusual events.
Explain.
In a survey of U.S. college students, 62% said that if their college offers new
programs tailored to the new economy, it will make them more likely to re-enroll.
You randomly select 39 college students. Find the probability that the number who
are more likely to enroll if their college offers new programs tailored to the new
economy is (a) exactly 24, (b) at least 29, and (c) at most 23.
YB Yes, because both np 25 and nq ≥ 5.
C. No, because np < 5.
(a) Find the probability that the number who are more likely to enroll if their
college offers new programs tailored to the new economy is exactly 24.
(Round to four decimal places as needed.)
