-6 to Chapter 7 < Question 8 of 25 > Find E(x) = . E(x) = (Round to the nearest tenth as needed.) Find the expected value of x using the sampling distribution of x. E(X)= (Round to the nearest tenth as needed.) Consider the population described by the probability distribution shown in the table. The random variable x is observed twice. Find E(x) = . Then use the sampling distribution of x to find the expected value of x. Click the icon to view the table.
