Consider the discrete random variable X given in the table below. Calculate the mean, variance, and standard deviation of X. Also, calculate the expected value of X. Round solution to three decimal places, if necessary.
x | 2 | 6 | 8 | 9 | 15 | 17 |
|---|---|---|---|---|---|---|
P(x) | 0.12 | 0.5 | 0.1 | 0.12 | 0.09 | 0.07 |
= 2= = What is the expected value of X
E(X)=
