Question

construct a scatter diagram using the data table. this data is from a study comparing the amount of tar and carbon monoxide (co) in cigarettes. use tar for the horizontal scale and use carbon monoxide (co) for the vertical scale. determine whether there appears to be a relationship between cigarette tar and co.
tar co tar co tar co
16 15 17 18 2 3
9 8 8 11 11 11
1 1 13 12 6 7
9 11 18 18 10 10
5 7 12 13 12 11
construct a scatter diagram.
a.
b.
c.
d.

Explanation:

Step1: Plot data points

We have pairs of (Tar, CO) values. For example, the first pair is (16, 15), we plot a point with x - coordinate 16 (Tar) and y - coordinate 15 (CO) on the graph. Repeat this for all pairs: (17,18), (2,3), (9,8), (8,11), (11,11), (1,1), (13,12), (6,7), (9,11), (18,18), (10,10), (5,7), (12,13), (12,11).

Step2: Analyze scatter - plot pattern

When we plot all the points, we observe that as the value of Tar increases, the value of CO also tends to increase. This indicates a positive linear relationship. Looking at the given options, the scatter - plot that shows this positive linear trend is the correct one.
