1). Determine the regression model that best fits the data, rounding all values to the nearest thousandth.  Then predict the size of a baby's head at 24 months old. Round your answer to the nearest tenth.
2). The pediatrician measured a newborns head and found the circumference to be 35.1cm.  Can he add the pair (0, 35.1) to the data set to calculate a new regression?
