Question 243224: We have a binomial experiment with p=.3 and n=2.
1)Set up the probability distribution by showing all x values and their associated probabilities.
2)Compute the mean, variance, and standard deviation. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! We have a binomial experiment with p=.3 and n=2.
1)Set up the probability distribution by showing all x values and their associated probabilities.
x::::P(x)
0::::2C0(0.3)^0(0.7)^2 = 0.7^2 = 0.49
1::::2C1(0.3)^1(0.7)^1 = 2*0.21= 0.42
2::::2C2(0.3)^2(0.7)^0 = 0.3^2 = 0.09
---------------------------------------------
2)Compute the mean, variance, and standard deviation.
mean = np = 2*0.3 = 0.6
variance = npq = 0.6*0.7 = 0.42
std = sqrt(npq) = sqrt(0.42) = 0.6481
