The mean is 2.4 children. (Round to one decimal place as needed.) Which of the following interpretations of the mean is correct? A. The observed ideal number of children will be equal to the mean ideal number of children for most adults. 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. Help me solve this View an example Get more help - Clear all
