Question

Usen-9, and p 0.25 to complete parts (a) through (c) belov. (a) ind the probabilities and construct a binomial probabiity distribution with the given parameters. (b) Compute the mean and standard deviation of the random variable. (c) aw the probability histogram, comment on its shape, and label the mean on the histogram a) To construct a binomial probability distribution, complete the table to the right. (Round to four decimal places as needed.) (b) Compute the mean and standard deviation of the random variable. ux Round to two decimal places as needed.) Gx Round to one decimal place as needed.

Explanation / Answer

a) n=9 and p=0.25

Then x follows Binomial (9,0.25)

b) Mean=np =2.25

standard deviation=1.299

c) Histogram

Option D is correct

x p(x) 0 0.075085 1 0.225254 2 0.300339 3 0.233597 4 0.116798 5 0.038933 6 0.008652 7 0.001236 8 0.000103 9 3.81E-06
