A company tests all new brands of golf balls to ensure that they meet certain specifications. One test conducted is intended to measure the average distance traveled when the ball is hit by a machine. Suppose the company wishes to estimate the mean distance for a new brand to within 1.5 yards with 90% confidence. Assume that past tests have indicated that the standard deviation of the distances the machine hits golf balls is approximately 11 yards. How many golf balls should be hit by the machine to achieve the desired accuracy in estimating the mean?
The machine should hit (________) golf balls to achieve the desired accuracy in estimating the mean.
(Round up to the nearest golf ball.)
Homework Answers

Problem 2 A sporting goods manufacturing company wanted to compare the distance traveled by golf balls produced using each of four different designs. Ten balls were manufactured with each design and were brought to the local golf course for the club professional to test. The order in which the balls were hit with the same club from the first tee was randomized so that the pro did not know which type of ball was being hit. All 40 balls were...

A golf ball manufacturer desires to compare the distance traveled by golf balls using four unique designs. Fifteen balls were manufactured and each was brought to the local golf course for testing by the local pro. The order of the golf balls hit by the professional was randomized so the pro did not know which ball was being hit. All 60 balls were hit over a short time period to reduce any potential environmental effects. Use the data provided to...

10-33. + The overall distance traveled by a golf ball is tested by hitting the ball with Iron Byron, a mechanical golfer with a swing that is said to emulate the distance hit by the legendary champion, Byron Nelson. Ten randomly selected balls of two different brands are tested and the overall distance measured. The data follow: Brand 1: 275, 286, 287, 271, 283, 271, 279, 275, 263,...

Does it matter what kind of tee a golfer places the ball on? A company that manufactures golf tees claims that the thinner shaft and smaller head of their tee will lessen resistance and drag, reducing spin and allowing the ball to travel farther. A golfing research facility compared the distance travelled by golf balls hit off regular wooden tees to those hit off the new tees. All the balls were struck by the same golf club using a robotic...
