Suppose the following data represent the ratings (on a scale from 1 to 5) for a certain smart phone game, with 1 representing a poor rating. Complete parts (a) through (d) below. (a) Construct a discrete probability distribution for the random variable x. Stars (x) P(x) 1 2 3 4 5 (Round to three decimal places as needed.) (b) Graph the discrete probability distribution. Choose the correct graph below. O A. 0.5- 0.4- 0.3- 0.2 0.1- 2 5 (c) Compute and interpret the mean of the random variable x. The mean is stars. (Round to one decimal place as needed.) Which of the following interpretations of the mean is correct? O B. 0.5 0.4- 0.3 0.2 0.1- Q O A. The observed value of an experiment will be equal to the mean of the random variable in most experiments. O B. The observed value of an experiment will be less than the mean of the random variable in most experiments. O C. As the number of experiments decreases, the mean of the observations will approach the mean of the random variable. O D. As the number of experiments increases, the mean of the observations will approach the mean of the random variable. C O C. 0.5- 0.4- 0.3- 0.2- 0.1- 0- Q O D. 0.5- 0.4- 0.3- 0.2 0.1+ 0- Q Stars Frequency 2385 2258 4298 4534 10.818 2345
