Scientists believe there is a link between ambient temperature and damage to a head gasket on a car. Using the provided information draw a scatterplot of the data. Based on the data, make an inference about if you should take your truck on a road trip to an area that has very low temperatures predicted for the time you will be there.

a
I would recommend that he does not go as higher temperatures have a strong positive correlation therefore the higher the temperature the more damage is caused.
b
I would recommend that he does not go as lower temperatures have a strong negative correlation, therefore the lower the temperature the more damage is caused.
c
I would recommend that he goes as there were many more temperatures with no damage than with damage.
d
I would recommend that he goes as lower temperatures have a strong positive correlation, therefore the lower the temperature the less damage is caused.

Answer 1

None of the options accurately reflect the inference that can be made from the data. A scatterplot of the data would need to be seen to make an informed decision about whether to take the truck on a road trip to an area with very low temperatures.
