The data relate to the growth of phytoplankton, bacteria, and similar microorga the water. (The variables are explained briefly on the back page of this handout.) For each of the graphs A. Give the explanatory variable and the response (dependent) variable and their ranges in the graph 8. Write out the equation of the trendline in Y-a+ b'x form with "a and "b" rounded to 2 decimal places C. Explain the interpretation of "b" in terms of the association between the two variables on the scatterplot. xpL var.> is Use the form aA b estimate of associated with a unit change in_ Explain how the calculated correlation coefficient number relates to what you see in the scatterplot Explain, based on the coefficient of determination and what you see in the scatterplot, how much confidence you would have in the estimate of "b" and why. indicates that a one unit change in- dep. var.
