A scatter plot is made with the data shown below: Number of Bakers at a Cake Shop 5 6 7 8 9 10 11 12 13 Number of Cakes Baked 7
7 8 8 9 11 13 14 14 What type of association will the scatter plot for these data represent between the number of bakers at the cake shop and the number of cakes baked? No association Positive linear association Negative linear association Positive nonlinear association
I think the correct answer would be the second option. Given the data above, the type of association that the scatter plot would show would be a positive linear association. It is best if you plot these points so you will see that there is an almost linear relation of the points. By doing linear regression, you can validate that the correlation of the data points would be linear. A positive linear association would mean that it changes linearly from the left increasing to the right. So, most likely, the graph would be sloping up to the right and it can be observed for the given data above.
Topics include the relationship between central, inscribed, and circumscribed angles; inscribed angles on a diameter are right angles; the radius of a circle is perpendicular to the tangent where the radius intersects the circle. Common Core: HSG-C.A.2
