Chapter 0, Problem 7.45(choose chapter or problem)
Weeds among the corn, continued. We can also use regression to analyze thedata on weeds and corn yield. The advantage of regression over the side-by-sidecomparison in the previous exercise is that we can use the fitted line to drawconclusions for counts of weeds other than the ones the researcher actually used.(a) Make a scatterplot of corn yield against weeds per meter. Find theleast-squares regression line and add it to your plot. What does the slope of thefitted line tell us about the effect of lambs-quarter on corn yield?(b) Predict the yield for corn grown under these conditions with 6 lambs-quarterplants per meter of row.
