Question

uct a scatter diagram using the data table to the right. this data is study comparing the amount of tar and carbon monoxide (co) in tes. use tar for the horizontal scale and use carbon monoxide (co) for tical scale. determine whether there appears to be a relationship en cigarette tar and co. full data set tar co tar co tar co 16 15 12 11 2 3 9 8 8 11 15 16 1 1 13 12 6 7 11 13 18 18 12 11 5 7 17 18 11 13 ... truct a scatter diagram. b. c. d. co co co co 20 20 20 20 16 16 16 16 12 12 12 12 8 8 8 8 4 4 4 4 0 0 0 0 0 4 8 12 16 20 tar 0 4 8 12 16 20 tar 0 4 8 12 16 20 tar 0 4 8 12 16 20 tar

Explanation:

Step1: Analyze Data Points

First, list the (Tar, CO) pairs from the table: (16,15), (9,8), (1,1), (11,13), (5,7), (12,11), (8,11), (13,12), (18,18), (17,18), (2,3), (15,16), (6,7), (12,11), (11,13).

Step2: Check Trend and Scatter Plot Match

Observe the relationship: as Tar increases, CO generally increases (positive correlation). Now check the scatter plots. The first plot (let's assume Option A, but from the visual, the left - most plot) should have points that show a positive trend. Let's check the axes: Tar (x - axis) and CO (y - axis). For low Tar (e.g., Tar = 1, CO = 1; Tar = 2, CO = 3), points are low. For high Tar (e.g., Tar = 16, CO = 15; Tar = 18, CO = 18), points are high. The first scatter plot (the one with points showing a positive upward trend as Tar increases) matches this. Assuming the first plot is Option A (the left - most one), it shows a positive linear relationship.

Answer:

The scatter plot that shows a positive relationship (as Tar increases, CO generally increases) is the left - most scatter plot (assuming it's Option A, with Tar on x - axis from 0 - 20 and CO on y - axis, points showing an upward trend with increasing Tar).
