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. Describe each data set, that is determine the shape, center, and spread.

Question
Describe each data set, that is determine the shape, center, and spread. 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 until it runs out of gas. He conducts this experiment 15 times on each car and records the number of miles driven. Sample mean for Car 1 Full data set D x= mi / 10 gal Car 1 (Type an integer or decimal rounded to one decimal place as needed.) 224 249 241 232 240 251 292 160 285 251 Sample mean for Car 2 159 308 285 306 285 mi / 10 gal (Type an integer or decimal rounded to one decimal place as needed.)

Sample standard deviation for Car 1 = mi / 10 gal (Type an integer or decimal rounded to one decimal place as needed.)
Sample standard deviation for Car 2 s= mi / 10 gal (Type an integer or decimal rounded to one decimal place as needed.) Which car would the customer buy and why? O A. Car 2, because it has a lower sample standard deviation, hence more predictable gas mileage. O B. Car 1, because it has a lower mean gas mileage. OC. Car 1, because it has a larger range of gas mileage. O D. There is very little difference between the two cars.
