Interpret the mean. Choose the correct answer below. O A. As the number of observations, n, decreases, the mean of the observations will approach the mean of the random variable. OB. The observed value of the random variable will be less than the mean of the random variable in most observations. O C. The observed value of the random variable will be equal to the mean of the random variable in most observations. OD. As the number of observations, n, increases, the mean of the observations will approach the mean of the random variable. b. Obtain the standard deviation of the random variable. 0x = (Round to three decimal place as needed.) c. Draw a probability histogram for the random variable. Choose the correct graph below. O A. ОВ.
