(a) Make a scatter diagram of the data and visualize the line you think best fits the data. 1000 140 120 960 900 80 120 140 100 xdowest pressure (in millibars 990 1000 xdowest pressure (in millibars Ⓡ ® (b) Would you say the correlation is low, moderate, or strong? low moderate strong Would you say the correlation is positive or negative? positive negative (c) Use a calculator to verify that Ex=5819, 2=5,648,339, y=575, ²64,683 and xy = 550,904. Computer. (Round your answer to four decimal places.) As x increases, does the value of r imply that y should tend to increase or decrease? Explain your answer. Given our value of r, we can not draw any conclusions for the behavior of y 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, y should tend to remain constant as x increases. 100 80 60 40 930 940 950 960 970 960 1000 980 960 940 40 60 80 100 120 xdowest pressure (in millibar 140 140 120 100 80 60 940 950 960 970 960 xdlowest pressure in millibars 990 1000
