Question

The scatter plot below shows data for the number of babies (y) born in a certain city in a given year, wherexis the number of years since2000. The least squares regression line is given byy=28,450344x.

The horizontal x axis represents the Year and ranges from 2002 to 2010, in increments of 2. The vertical y axis represents the Number of Babies Born, and ranges from 20000 to 30000, in increments of 2000. The coordinates of the points are as follows: (2003, 28500), (2005, 25000), (2007, 27500), (2009, 27000) and (2010, 25000). The downward sloping line begins at the graphed point (2003, 28500), goes down to the right, and ends at the graphed point (2010, 25000). All values are estimated.

Interpret they-intercept of the least squares regression line.

Select the correct answer below:

The predicted number of babies born in the year0is28,450.

The predicted number of babies born in the year2000is344.

The predicted number of babies born in the year2002is28,450.

They-intercept should not be interpreted.
