Tees Does it matter what kind of tee a golfer places theball on? The company that manufactures “Stinger” teesclaims that the thinner shaft and smaller head will lessendrag, reducing spin and allowing the ball to travel farther.In August 2003, Golf Laboratories, Inc., compared thedistance traveled by golf balls hit off regular wooden teesto those hit off Stinger tees. All the balls were struck bythe same golf club using a robotic device set to swing theclub head at approximately 95 miles per hour. Summarystatistics from the test are shown in the table. Assumethat 6 balls were hit off each tee and that the data weresuitable for inference.Is there evidence that balls hit off the Stinger tees wouldhave a higher initial velocity?

An instructor for a test preparation course claims that the course will improve the test scores of students. The table shows the critical reading scores for 14 students the first two times they took the test. Before taking the test for the second time, the students took the instructor's course to try to improve their critical reading test scores. At a = 0.01, is there enough evidence to support the instructor's claim? Complete parts (a) through (f).
