The mean is 0 children. (Round to one decimal place as needed.) Which of the following interpretations of the mean is correct? O A. If many adults were surveyed, one would expect the mean ideal number of children to be the mean of the random variable. O B. The observed ideal number of children will be less than the mean ideal number of children for most adults. O C. If any number of adults were surveyed, one would expect the mean ideal number of children to be the mean of the random variable. O D. The observed ideal number of children will be equal to the mean ideal number of children for most adults. (d) Compute the standard deviation of the random variable X.
