Interpolation and Extrapolation

The scatter plot shows the relationship between the number of chapters and the total number of pages for several books.  Use the trend line to predict how many chapters would be in a book with 180 pages. 

• 12 chapters
• 15 chapters
• 18 chapters
• 21 chapters

Select the statement that best describes the line.

• The line is the line of best fit.
• The line is NOT a line of best fit because it does not pass through two points.
• The line is NOT a line of best fit because it does not go through the middle of the data set.
• The line is NOT a line of best fit because it does not go through the origin.

A positive correlation between two variables means...

• that as one variable increases, the other variable also increases

• that as one variable increases, the other variable decreases

• that as one variable decreases, the other variable increases

• the two variables are happy
