Determine the indicated probability for a binomial experiment with the given number of trials n and the given success probability p. Then find the mean, variance, and standard deviation.

18.	n = 10, p = 0.2, P(1)
20.	n = 14, p = 0.3, P(8)
22.	n = 6, p = 0.8, P(6)
24.	n = 15, p = 0.9, P(14 or more)
26.	n = 30, p = 0.9, P(More than 27)

Expert Solution

for Binomial(n,p)

mean = np

variance = np(1-p)

std dev = square root of ( np(1-p))

Sr.no	n	p	Mean = np	Variance=npq	std dev = sqrt(npq)
1	10	0.2	2.0	1.6	1.26
2	14	0.3	4.2	2.94	1.71

We have a binomial experiment with n = 18 trials, each with probability p = 0.15 of a success. A success occurs if a student withdraws from a class, so the number of successes, x, will take on the values 0, 1, and 2. The probability of each x value, denoted f(x), can be found using a table like the one below. Note that these values are rounded to four decimal places. n x p 0.10 0.15 0.20 0.25 18...

When the number of trials, n, is large, binomial probability tables may not be available. Furthermore, if a computer is not available, hand calculations will be tedious. As an alternative, the Poisson distribution can be used to approximate the binomial distribution when n is large and p is small. Here the mean of the Poisson distribution is taken to be μ = np. That is, when n is large and p is small, we can use the Poisson formula with...

4.) Determine whether the following probability experiment is a binomial experiment. If the probability experiment is not a binomial experiment, state why? a.) In a town with 400 citizens, 100 randomly selected citizens are asked to identify their religion. The number who identify with a Christian religion is recorded. b.) An experiment is conducted in which a single die is cast until a 3 comes up. The number of throws required is recorded.

Let N be a binomial random variable with n = 2 trials and success probability p = 0.5. Let X and Y be uniform random variables on [0, 1] and that X, Y, N are mutually independent. Find the probability density function for Z = NXY . Hint: Find P(Z ≤ z) for z ∈ [0, 1] by conditioning on the value of N ∈ {0, 1, 2}.

Consider a binomial experiment. If the number of trials is increased, what happens to the expected value, if the number of trials is decreased, what effect would occur? With regard to the standard deviation, illustrate how and why the larger the deviation number, the more difficult it would be to predict an outcome. Use specific examples to illustrate.

Consider a binomial experiment with 20 trials and probability 0.35 of success on a single trial. (a) Use the binomial distribution to find the probability of exactly 10 successes. (Round your answer to three decimal places.) (b) Use the normal distribution to approximate the probability of exactly 10 successes. (Round your answer to three decimal places.) (c) Compare the results of parts (a) and (b). These results are fairly different. These results are almost exactly the same.
