(6 points) Cars on Campus. Statistics students at a community college wonder whether the cars belonging to students are, on average, older than the cars belonging to faculty. They select a random sample of 23 cars in the student parking lot and find the average age to be 8.5 year with a standard deviation of 5.3 year. A random sample of 23 cars in the faculty parking lot have an average age of 3.4 years with a standard deviation of...
