Use n = 6 and p = 0.65 to complete parts (a) through (d) below. (a) Construct a binomial probability distribution with the given parameters. P(x) X 0 1 2 3 4 5 6 (Round to four decimal places as needed.) (b) Compute the mean and standard deviation of the random variable using µx = Σ[x • P(x)] and ox=√√Σ[x² • P(x)] −µ² · (Round to two decimal places as needed.) (Round to two decimal places as needed.) (c) Compute the mean and standard deviation, using μx = np and ox=√/np(1-P). (Round to two decimal places as needed.) (Round to two decimal places as needed.) Hx= 0x = Hx= 0x = (d) Draw a graph of the probability distribution and comment on its shape. Which graph below shows the probability distribution? O A. AP(x) 0.5- 0.25- 0 3 6 Q O B. AP(x) 0.5- 0.25- 0+⁹+ 0 3 6 Q O C. AP(x) 0.5- 0.25- •m 0 3 -6 Q LY O D. AP(x) 0.5- 0.25- 0 3 -co Q M
