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.

construct a scatter diagram.
is there a relationship between cigarette tar and co?
a. yes, as the amount of tar increases the amount of carbon monoxide also increases
b. yes, as the amount of tar increases the amount of carbon monoxide also increases
c. no, there appears to be no relationship.

Explanation:

Step1: Analyze scatter - plot construction

We plot each pair of (Tar, CO) values from the data table on a graph with Tar on the x - axis and CO on the y - axis.

Step2: Observe the pattern in the scatter - plot

When we look at the plotted points, we can see that as the value of Tar increases, the value of CO also tends to increase.

Answer:

A. Yes, as the amount of tar increases the amount of carbon monoxide also increases
