An illustration of a scatterplot shows x on x-axis from 65 to 75 in increments of 1 and y on the y-axis from 200 to 240 in increments of 2.5. Eleven points are plotted. The approximate plotted points are as follows: left parenthesis 65 comma 205 right parenthesis, left parenthesis 67 comma 216 right parenthesis, left parenthesis 68 comma 210 right parenthesis, left parenthesis 68 comma 218 right parenthesis, left parenthesis 69 comma 224 right parenthesis, left parenthesis 70 comma 220 right parenthesis, left parenthesis 70 comma 224 right parenthesis, left parenthesis 71 comma 230 right parenthesis, left parenthesis 72 comma 235 right parenthesis, left parenthesis 74 comma 200 right parenthesis, and left parenthesis 74 comma 240 right parenthesis.

Is there a relationship between the two sets of data? How do you know?

To determine if there is a relationship between the two sets of data based on the scatterplot, we consider the positioning of the plotted points relative to a trend line. The points described suggest a general upward trend in the y-values (y-axis) as x-values (x-axis) increase, which indicates a positive correlation.

Since the points are described as being close to a trend line, we can conclude that there is a relationship. Therefore, the correct response is:

Yes, because the data points are close to the trend line.
