Graph shows the number of people painting a room and the time it takes to paint the room,

True or False:

The scatter plot does not appear to have any clustering.

• True

• False

The scatter plot shows the number of people painting a room and the time it takes to paint the room.

Describe the association.

• Positive

• Negative

• None

Answer explanation

The association between the number of people painting a room and the time it takes to paint the room is negative, as the scatter plot shows that as the number of people increases, the time taken decreases.
