The image you uploaded contains questions from a quiz about bivariate statistics, specifically scatter diagrams (diagram pencar). Let me help you understand and solve the questions in the image.

Question 1:

It asks for the correct statement regarding the scatter diagram that shows the relationship between weight ("Berat Badan") and height ("Tinggi Badan") of several teenagers. The options are:

a) The relationship between weight and height is uncertain.
b) Weight tends to increase as height decreases.
c) Weight tends to increase as height increases.
d) Weight and height vary according to teenage age.
e) Weight tends to decrease as height increases.

From the diagram, we can infer the trend that as height increases, weight also tends to increase, making option (c) the most accurate answer.

Question 2:

It asks about the relationship between the values of x and y in the scatter diagram. The options are:

a) No relationship
b) Nonlinear relationship
c) Positive linear relationship
d) Negative linear relationship

By looking at the plot, it appears that as x increases, y also increases, suggesting a positive linear relationship. Therefore, the answer is (c) Positive linear relationship.
