Consider the scatterplot of two different graphs give below. Test 2 vs. Test 1 0 Test 2 0.734*x + 23 105 I 85 TestZ O 65 o' 45 50 60 70 80 90 100 Test 1 The trendline is also written on the graph, it is y=0.734x+23. a. Does it make sense that the trendline has positive slope? Why or why not? b. Since the slope is 0.73 what can you conclude about these two test? (On which one did the students do better, for example.)
