This data is the ages of mothers.

The ages in the sample have presumably been rounded down since eg a mother aged 27 3/4 would have given her age as 27. What effect will this have on your estimate of the mean and standard deviation? Suggest possible corrections to the estimates, distinguishing clearly between the corrected and the uncorrected value.
