They gathered data from past years and made the following table: YearProfit (in thousands of dollars)2000125200114120021522003160200416320051672006171 1) On the graph below, create a scatter plot of the data from the table. Be sure to accurately label your axes.  2) Describe the correlation. 3) Which variable is the explanatory variable? Which is response variable? How do you know? 4) The Keanes estimated that their bakery would earn a profit of $175,000. Do you agree or disagree with their estimate? Why? TV & Test Scores: Students wanted to know how the hours of TV they watched yesterday relates to their scores on todays test. Fifteen students participated in the study. Below is a table of the data they collected.
