The mean is 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. B. If any number of adults were surveyed, one would expect the mean ideal number of children to be the mean of the random variable. OC. The observed ideal number of children will be equal to the mean ideal number of children for most adults. D. The observed ideal number of children will be less than the mean ideal number of children for most adults. (d) Compute the standard deviation of the random variable X. The standard deviation is children. (Round to one decimal place as needed.)
