A company produces scooters used by small businesses that find them convenient for making short deliveries. The company is notified whenever a scooter breaks down, and the problem is classified as being either mechanical or electrical. The company then matches the scooter to the plant where it was assembled. The data table to the right contains a random sample of 200 breakdowns. Use the data file and the relative frequency assessment method to complete parts a through c. Electrical Mechanical Total Plant 1 21 52 73 Plant 2 74 53 127 Total 95 105 200 a.

Are SAT mathematics scores a good indicator of college success? All of us have taken one or more academic aptitude tests as part of a college admission procedure. The admissions staff at your college used the results of these tests to determine your admission status. Table 1.9 gives the SAT math scores from a test given before admission to college and the GPAs at college graduation for a random sample of 11 students at one small private university in the Midwest. Construct a scatter plot and determine what information it provides.
