Question: For a statistics project, a group of students wonder if there is a difference In the number of French fries two different drive-thru's serve. They randomly select a day and time to purchase five orders of fries from each drive-thru. They make a dot plot of the data and the label on the x-axis as "number of fries in one bag/order". There is one dot plot for each of the two drive-thru's. What is the response variable and the explanatory variable?
Why I'm asking: I was confused with this because if the explanatory variable is what you use and the response variable is what you predict, shouldn't the explanatory variable be the drive-thru and the response variable be the fries because you should use the drive-thru to predict how many fries you will receive? You can't use the count of fries to predict a drive-thru. The x-axis should be labeled always with the explanatory variable but you can't label the bottom of a dot plot with a drive-thru, it has to be count of fries. Looking for somebody to explain this a bit for me....
