Car's Fuel Efficiency Source: Rossman/Chance WorkShop Statistics, 2d ed The following talbe reports the EPA'a cit miles per gallon rating and the weight (in pounds) for the sports cars descried in Consumer Reports 1999 New Car Buying Guide. (EPA rating for Audi was not reported) Model City MPG City MPG Weight Model Mazda MX-5 Miata 2365 Audi TT BMW 318ti BMW Z3 Chevrolet Camaro Chevrolet Corvette Ford Mustang Honda Prelude Hyundai Tiburon 30 26 19 17 17 17 22 22 City Mpg 25 20 Weight 2655 2790 2960 3545 3295 3270 3040 2705 A] Identify the Observational Units here How many variables are reported in the table for each observational unit? Identify the variables and indentify each variable's type (Categorical or Quantitative). B] Use the axes below to construct a scatterplot of miles per gallon vs weight. Miles per Gallon vs Weight T The simplest graph for displaying two quantitative variables multaneously is a scatterplot. A dot is placed for each observational pair at the intersection of its two values. 2000 Mercedes Benz SLK Mercury Cougar Mitsubishi Eclipse Pontiac Firebird Porsche Boxster Saturn SC Toyota Celica 3000 Weight The variable to be predicted (the Response Variable) usually is placed on the vertical axis and the variable to do the predicting (the Explanatory Variable) is on the horizontal axis. 25 22 20 4000 23 18 19 27 22 3020 3140 3235 3545 2905 2420 2720 C] Does the scatterplot reveal any relationship between a car's weight and its fuel efficiency? In other words, does knowing a car's weight reveal any information about its fuel efficiency? Briefly describe the relationship between the two variables. D] Is fuel efficiency positively or negatively associated with weight? _____ Explain what this means in context. Can you find an example where one car weighs more than another and still manages to have better fuel effiency than the other car? Circle the dot on the scatterplot you made.
