(in cm)
1
35.8cm
2
36.6
5
38.5
6
39.1
4
38.9
13
40.1
7
39.1
15

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?
