Question

9 multiple choice 1 point what type of correlation is shown on the graph? blood pressure 150 140 130 120 110 100 20 25 30 35 40 45 50 55 60 65 70 age of adults positive correlation perfect positive correlation no correlation negative correlation

Explanation:

As age of adults increases, blood - pressure generally shows an upward trend, but not in a perfectly linear way. In positive correlation, as one variable increases, the other variable also tends to increase. Here, as age (one variable) increases, blood - pressure (the other variable) increases, so it is a positive correlation. A perfect positive correlation would have all points in a straight - line, which is not the case here.

Answer:

positive correlation
