Use the following information to answer A researcher wants to investigate whether older drivers' break response times differ from younger drivers. He obtains a sample of 12 older drivers and finds that they have an average break response time of 5 seconds and a sum of squares of 25. The researcher also measures an average break response time of 2.5 seconds for 7 younger drivers with a sum of squares of 20. Conduct the appropriate t test with an alpha of .05. Which of the following is the correct alternative hypothesis? (Do not let your assumptions about drivers influence your answer. Only use information given in the problem to answer this question.)
