Indicate clearly the methods you use, because you will be scored on the correctness of your methods as well as on the accuracy and completeness of your results and explanations. Correct answers without supporting work may not receive credit.  \nYou may use a handheld calculator in this section. Use of a handheld graphing calculator is expected.  \nReference information, including lists of formulas and tables, is available in this application and can be accessed throughout the exam.  \nYou may pace yourself as you answer the questions in this section, or you may use these optional timing recommendations:  \nIt is suggested that you spend about 1 hour and 5 minutes on questions 1 through 5 and about 25 minutes on question 6.  \nYou can go back and forth between questions in this section until time expires.

The manager of an automotive company is interested in comparing the gas mileages for cars manufactured in Country A and cars manufactured in Country B. The manager selected a random sample of 100 cars manufactured in Country A and a random sample of 100 cars manufactured in Country B. The gas mileages for each sample, in miles per gallon (mpg), are summarized in the boxplots.  \nBoxplots of Gas Mileage for Each Country  \nA. Compare the distributions of gas mileage for the sample of cars manufactured in Country A and the sample of cars manufactured in Country B.  \nB. For the distribution of gas mileage for the sample of cars manufactured in Country A, would you expect the mean to be greater than 18 mpg, less than 18 mpg, or equal to 18 mpg? Justify your answer.  \nC. The manager will create a new boxplot with the combined data from the sample of cars manufactured in Country A and the sample of cars manufactured in Country B.  \ni. What is the range of the combined data set? Justify your answer.  \nii. What is a possible value of the median of the combined data set? Justify your answer by referencing the boxplots shown.  \n© 2025 College Board.  \n[Visit College Board on the web:](Visit College Board on the web: collegeboard.org 3)[ collegeboard.org](Visit College Board on the web: collegeboard.org 3)[ 3](Visit College Board on the web: collegeboard.org 3)  \nAP STATISTICS 2025 n FREE-RESPONSE QUESTIONS  \n2.
