The values listed below are waiting times (in minutes) of customers at two different banks. At Bank A, customers enter a single waiting line that feeds three teller windows. At Bank B, customers may enter any one of three different lines that have formed at three teller windows. Answer the following questions.

2. A.) Find the 5-number summary for the data. B.) Is the data discrete or continuous?

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.   Full data set    Car 1 216 243 205 242 239 297 295 172 270 251 165 310 265 316 278   Car 2 231 220 223 205 245 257 242 292 248 252 287 255 250 293 251   Median for Car 2 M=___________mi​ / 10 gal ​(Type an integer or decimal rounded to one decimal place as​ needed.)

An engineer wants to determine how the weight of a gas powered car, x, affects gas mileage, y. The accompanying days represent the weights of various domestic cars and their miles per gallon in the city for the most recent model year. weight                    Miles per (pounds), x           Gallon, y 3797                             16 3897                             16 2704                             24 3608                             20 3360                             22 3040                             22 3787                              17 2618                              24 3509                             18 3798                             16 3399                             17   interpret the slope y-intercept, if appropriate.
