Chapter 0, Problem 24.3(choose chapter or problem)
(a) Make a scatterplot of river discharge against time. Is there a clearincreasing trend? Calculate r 2 and briefly interpret its value. There isconsiderable year-to-year variation, so we wonder if the trend is statisticallysignificant.(b) As a first step, find the least-squares line and draw it on your plot. Then findthe regression standard error s, which measures scatter about this line. We willcontinue the analysis in later exercises.
