Question 10 2 pts The probabilities of the discrete random variable X are taking values shown in the table: X 2 4 6 8 10 PIX=x) 0.18 0.31 0.34 0.10 0.07 What is the standard deviation of the distribution? (Round your answer to the third decimal place) O 2.214 0.200 6.000 O 0.121 Not enough information to answer the question O 10.000 None of the given numerical values is correct 03.162
A random variable X assumes values 1, 2, 3 and 4 with probabilities: 0.34, 0.18, 0.25, and ...? respectively. Calculate the standard deviation of the random variable. Answer to four decimals.
Let X be a discrete random variable taking integer values 1, 2, ..., 10. It is also known that: P(X < 4) = 0.57, PCX 2 4) = 0.71. Then P(X = 4) = A: 0.14|B: 0.28 |C: 0.45 OD: 0.64|E: 0.73 OF: 0.95 Submit Answer Tries 0/5
Suppose X is a random variable taking on possible values 1,2,3 with respective probabilities.4, .5, and .1. Y is a random variable independent from X taking on possible values 2,3,4 with respective probabilities .3,.3, and 4. Use R to determine the following. a) Find the probability P(X*Y = 4) b) Find the expected value of X. c) Find the standard deviation of X. d) Find the expected value of Y. e) Find the standard deviation of Y. f) Find the...
X is a Discrete Random Variable that can take five values Given The five possible values are: x1 = 4 (Units not given) X2 = 6 (Units not given) X3 = 9 (Units not given) X4 = 12 (Units not given) X5 = 15 (Units not given) The associated probabilities are: p(x1) = 0.14 (Unitless) p(x2) = 0.11 (Unitless) p(x3) = 0.10 (Unitless) p(xx) = 0.25 (Unitless) Question(s) 1. If the five values are collectively exhaustive, what is p(x5)? (Unitless)...
