The following table shows the approximate numbers of school goers in the United States (residents who attended some educational institution) in 1998 , broken down by age group. Use the rounded midpoints of the given measurement classes to compute the probability \( P \) distribution of the age \( X \) of a school goer. (Round probabilities to four decimal places.) Compute the expected value of \( X, E(X) \). (Round your answer to one decimal place.) \[ E(X)=\quad \times \] What information does the expected value give about residents enrolled in schools? (Round your answer to one decimal place.) \[ \text { In 1998, was } \ \text { years old. } \]
