Suppose the number of married men (in thousands) between the ages of 20 and 44 in the United States in a certain year is given in the following table.

Age    20-24    25-29    30-34    35-39    40-44

Men    1292    4119    6275    7518    7673

Find the mean and the standard deviation of the given data. Hint: Assume that all ages lying within a group interval take the middle value of that group. (Round your answers to two decimal places.)
