Suppose that a customer is purchasing a car. He conducts an experiment in which he puts 10 gallons of gas in the car and drives it until it runs out of gas. He conducts this experiment 15 times on each car and records the number of miles driven. Car 1 240 202 230 219 241 289 284 246 254 246 247 251 270 251 293

Car 2 249 210 246 231 251 163 219 275 170 279 272 316 306 286 294 Part 1 Describe each data set, that is determine the shape, center, and spread. Sample mean for Car 1 x overbar =_________ ________ mi / 10 gal (Type an integer or decimal rounded to one decimal place as needed.)

Sample mean for Car 2 x overbar +_______ _________ mi / 10 gal (Type an integer or decimal rounded to one decimal place as needed.)

Part 2 Median for Car 1 M =________ _________mi / 10 gal (Type an integer or decimal rounded to one decimal place as needed.)

Median for Car 2 M=_______ __________ mi / 10 gal (Type an integer or decimal rounded to one decimal place as needed.)

Part 3 Range for Car 1 R=________________________________ _________ mi / 10 gal (Type an integer or decimal rounded to one decimal place as needed.)

Range for Car 2 R=______ ________ mi / 10 gal (Type an integer or decimal rounded to one decimal place as needed.)

Part 4 Sample standard deviation for Car 1 s=________________________________ _________ mi / 10 gal (Type an integer or decimal rounded to one decimal place as needed.)

Sample standard deviation for Car 2 s=______ _______e mi / 10 gal (Type an integer or decimal rounded to one decimal place as needed.)

Part 5 Which car would the customer buy and why? A. Car 1, because it has a lower sample standard deviation, hence more predictable gas mileage. B. Car 2, because it has a larger range of gas mileage. C. Car 2, because it has a lower mean gas mileage. D. There is very little difference between the two cars.
