The table below gives the birth weights of five randomly
selected mothers and the birth weights of their babies. Using this
data, consider the equation of the regression line, yˆ=b0+b1x, for
predicting the birth weight of a baby based on the mother's birth
weight. Keep in mind, the correlation coefficient may or may not be
statistically significant for the data given. Remember, in
practice, it would not be appropriate to use the regression line to
make a prediction if the...
