When creating the dot plot, how are multiple data points for a single score displayed? a. A larger size dot is used; the size of the dot is directly proportional to the number of data points. b. More than one dot is used; dots are placed side by side creating a wider interval. c. A dot plot is innappropriate when multiple data points exist for a single score. d. Multiple dots, representing each data point, are replaced on top of one another.
The cost of fuel is the largest component of cost of ownership for most vehicles. Fuel cost is (almost) inversely proportional to gas mileage; higher gas mileage means lower fuel cost and vice-versa. If you keep track of the number of miles driven on each tank of gas as well as how much gas is purchased, it is easy to calculate gas mileage; many cell phone apps exist to track this. The data in the following table is the gas mileage for Mr. Hebert's 2015 Jeep Wrangler Unlimited. 12.85 14.98 15.36 17.09 18.86 13.28 15.11 15.62 17.50 19.07 13.48 15.12 15.65 17.66 20.91 14.65 15.13 16.41 18.17 21.17 14.71 15.14 16.80 18.27 22.11 e.
