Quastlon 12 10 points Save A least-squares multiple linear regression model was t for 20 observations taken from mothers that were between 21 and 50 weeks pregnant. The model predicted infant birth weight(in pounds) from gestational age (weeks) and estriol level (measuredjust before birth from the mothers?) 5 urine). The resulting regression equation is given by y=7.6047 - 0.0073 Xgestage + 0.1148 Xestrilo The investigator wants to know what the predicted average infant birth weight for a fetus at 6 weeks of gestation with an estriol level of 47. Select the most appropriate response. 0 23.913 pounds 0 12.9565 pounds 0 11.9555 pounds 0 This regression equation should not be used for this purpose as the observations used were all from women who were at 21 to 50 weeks gestation.
