Homework: Homework 4: 4.1-4.3 Score: 0 of 5 pts 4.3.41 7 of 10 (6 complete) HW Score: 4 Consider the following binomial probability distribution p(x)-| | (0.45)x(0.55)5-x (x=0, 1, 2, 5) a. Is x a discrete or a continuous random variable? b. Graph the probability distribution. c. Find the mean and standard deviation of x. a. Is x a discrete or a continuous random variable? Choose the correct answer below 0 Continuous y Discrete b. Graph the probability distribution. Choose the correct graph below. OA. O B. O C. OD. Apx) 0.5- 0. Click to select your answer and then click Check Answer.

Explanation / Answer

b) Option B is Correct because distribution will be like symmetric distribution

c) Mean = 0.45*5 = 2.25

Standard Deviation = SQRT(5*0.45*0.55) = 1.11 (rounded to two decimal places)
