Stars 1 2540 2568 4399 4685 10,182 1 1 2 4 5 2. 3 4 (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 A. The observed value of an experiment will be equal to the mean of the random variable in most experiments. O B. As the number of experiments decreases, the mean of the observations will approach the mean of the random variable. OC. As the number of experiments increases, the mean of the observations will approach the mean of the random variable. O D. The observed value of an experiment will be less than the mean of the random variable in most experiments. (d) Compute the standard deviation of the random variable x. The standard deviation is stars. (Round to one decimal place as needed.) N34 5
