The graph below is a plot of the fuel efficiency (in miles per gallon,or mpg)of various cars versus the weight of these cars (in thousands of pounds). The points denoted by the plotting symbol × correspond to pick-up trucks and SUVs.The points denoted by the plotting symbol . correspond to automobiles (sedans and station wagons).What can we conclude from this plot?
A)There is little difference between trucks and automobiles.
B)Trucks tend to be higher in weight than automobiles.
C)Trucks tend to get poorer gas mileage than automobiles.
D)The plot is invalid.A scatterplot is used to represent quantitative variables,and the vehicle type is a qualitative variable.
E)Both B and C

Quizplus · Accepted Answer

From the plot, it can be observed that the points denoted by × (pick-up trucks and SUVs) tend to be higher in weight than the points denoted by ● (sedans and station wagons). Additionally, the points denoted by × tend to have lower fuel efficiency (poorer gas mileage) than the points denoted by ●. Therefore, the best choice is E which states that trucks tend to be higher in weight than automobiles and tend to get poorer gas mileage than automobiles.
