A. The observed value of the random variable will almost always be equal to the mean of the random variable. B. As the number of trials n decreases, the mean of the observations will approach the mean of the random variable. C. The observed value of the random variable will almost always be less than the mean of the random variable. D. As the number of trials n increases, the mean of the observations will approach the mean of the random variable (b) Compute the standard deviation of the random variable X ?x= _____ (round to one decimal place as needed
