Do baseball teams that score more runs sell more tickets to their games? Identify response variable and predictor.
Response (Y, dependent variable) = # Runs, Predictor (X,independent variable)= # Tickets 

Response (Y, dependent variable) = #Tickets, Predictor (X,independent variable)= # Runs 

Response (Y, independent variable) = # Runs, Predictor (X,dependent variable)= # Tickets 

Response (Y, independent variable) = #Tickets, Predictor (X,dependent variable)= # Runs 
Scatterplot. Select all statements that are true about a scatterplot:
A scatterplot can be used to detect if a response is normally distributed. 

A scatterplot is a graph of data from two categorical variables. 

A scatterplot cannot be used to detect the direction of linear association. 

A scatterplot is used for detecting patterns, strength of association, and influential points. 

A scatterplot is a graph of data from two continuous quantitative variables.

1. Correlation DOES NOT imply causation.
2. Which of the values cannot represent correlation? Select ALL that apply.
Correlation ranges from 1 to 1 ( 0 included, and endpoints included)
1.0001  can't exist
0.5  can exist
0  can exist
1/3  can exist
73  can't exist
3. Do baseball teams that score more runs sell more tickets to their games? Identify response variable and predictor.
Answer: Response (Y, dependent variable) = #Tickets, Predictor (X,independent variable)= # Runs
