(C) Compute and interpret the mean of the random variable x. Hx =hits (Type an integer or a decimal. Do not round.) Which of the following interpretations of the mean is correct? O A. 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 B. The observed number of hits per game will be less than the mean number of hits per game for most games. O C. In any number of games, one would expect the mean number of hits per game to be the mean of the random variable. O D. The observed number of hits per game will be equal to the mean number of hits per game for most games. (d) Compute the standard deviation of the random variable X. o,= hits (Round to three decimal places as needed.) (e) What is the probability that in a randomly selected game, the player got 2 hits? (Type an integer or a decimal. Do not round.) (f) What is the probability that in a randomly selected game, the player got more than 1 hit?
