    217.33 Ib

    Step-by-step explanation:

    The mean of a set of numbers is the ratio of the total of these numbers to the number of numbers added. As such where there are x numbers and the sum of these numbers is T, the mean is

    = T/x

    If the mean weight of 3 outfielders on the baseball team is 194 lb, the total weight of the 3 outfielders

    = 194 * 3

    = 582 Ib

    the mean weight of the 6 other players is 229 lb, the total weight of the 6 outfielders

    = 229 * 6

    = 1374 Ib

    Total weight of the 9 players

    = 1374 Ib + 582 Ib

    = 1956 Ib

    Mean of 9 person team

    = 1956/9

    = 217.33 Ib
