y (average weight (in kg)) 160 140 120 100 80 (a) Make a scatter diagram of the data and visualize the line you think best fits the data. (b) Would you say the correlation is low, moderate, or strong? low moderate strong (0) use a calculator to verify that Ex = 59, Ex2 = 943, Er = 626, I y2 = 87,486, and y xy=8,843. Compute r. (Round your answer to four decimal places.) As x increases from 3 to 23 months, does the value of r imply that y should tend to increase or decrease? Explain your answer. Given our value of r, y should tend to remain constant as x increases. Given our value of r, y should tend to decrease as x increases. Given our value of r, y should tend to increase as x increases. Given our value of r, we can not draw any conclusions for the behavior of y as x increases
