The effective delivery and care of newborn babies can be aided by accurate estimates of birth weight. A study [6] attempted to predict the birth weight of babies for 11 women with abnormal pregnancies by using echo-planar imaging (EPI) up to 1 week before delivery to estimate each baby’s fetal volume. Draw a scatter diagram and use least squares estimates of the regression model to see if there is a statistically significant relationship at the 1 percent level between the child’s estimated fetal volume X (decimeters cubed) and the birth weight Y (kilograms), both of which are in Table 8.4. Summarize your findings, and be sure to interpret the estimated slope of your fitted line.
