Question 21 5 pts Greene & Touchstone conducted a study to relate birth weight to the estriol levels from 24-hour urine specimens taken from pregnant women who are near term. The test can provide indirect evidence of an abnormally small fetus. The scatter plot of the data is shown below. We want to perform a statistical test to find linear relationship between birth weight and estriol levels. Linear regression result shows that y = 21.52 +...
