In the probability distribution to the right, the random variable X represents the number of hits a baseball player obtained in a game over the course of a season. Complete parts (a) through (f) below. x P(x) 0 0.1673 1 0.3349 2 0.2867 3 0.1487 4 0.0388 5 0.0236 (a) Verify that this is a discrete probability distribution. This is a discrete probability distribution because ▼ all of the probabilities are at least one of the probabilities is between nothing and nothing, inclusive, and the ▼ mean product sum of the probabilities is (Type whole numbers.

The observed number of hits per game will be less than the mean number of hits per game for most games. B. Over the course of many games, one would expect the mean number of hits per game to be the mean of the random variable. O C. The observed number of hits per game will be equal to the mean number of hits per game for most games. O D. In any number of games, one would expect the mean number of hits per game to be the mean of the random variable.

Which of the following tables represents a valid discrete probability distribution? X P(X=x) X P(X=X) X P(X=x) X P(X=x) 5 0.51 1 0.23 0 10 15 0.03 0.03 3 0.03 1 0.33 0.15 3 0.24 5 0.15 2 0.27 20 0.39 7 9 0.17 0.19 3 0.19 25 30 0.15 0.01 12 11 0.02 4 5 1.01 0.06 6 9 15 18 0.22 0.23 0.12 -0.03 0.43
I am in Prob/Stat! Find the standard deviation of this probability distribution. Give your answer to at least 2 decimal places. x P(x) 0 0.15 1 0.15 2 0.2 3 0.5 I have multiplied P by x, thus, P(x) as such: 0.15(0) = 0 0.15(1) = 0.15 0.2(2) = 0.4 0.5(3) = 1.5 I then add the four together to get the sum of; 2.05. What am I doing wrong? Am I not finding the standard deviation correctly?? Thank you in advance!
Only need D-F.
