The observed value of an experiment will be equal to the mean of the random variable in mo OB. As the number of experiments decreases, the mean of the observations will approach the m O C. The observed value of an experiment will be less than the mean of the random variable in m D. As the number of experiments increases, the mean of the observations will approach the me (d) Compute the standard deviation of the random variable x. The standard deviation is activities. (Round to one decimal place as needed.)
