Here sample 1 is new type of golf ball (sample A)
and sample 2 is standard golf ball (sample B)
here we need to use the independent 2-sample t-test
first we need to find the mean and standard deviation for sample 1 and sample 2

A golf association requires that golf balls have a diameter that is 1.68 inches. To determine if golf balls conform to the standard, a random sample of golf balls was selected. Their diameters are shown in the accompanying data table. Do the golf balls conform to the standards? Use the c = 0.05 level of significance.

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...
(1 point) Golf course designers have become concerned that old courses are becoming obsolete since new technology has given golfers the ability to hit the ball so far. Designers, therefore, have proposed that new golf courses need to be built expecting that the average golfer can hit the ball more than 235 yards on average. Suppose a random sample of 151 golfers be chosen so that their mean driving distance is 234.7 yards. The population standard deviation is 40.9. Use...

Question 6 Golf-course designers have become concerned that old courses are becoming obsolete since new technology has given golfers the ability to hit the ball so far. Designers, therefore, have proposed that new golf courses need to be built expecting that the average golfer can hit the ball more than 230 yards on average. A random sample of 177 golfers show that their mean driving distance is 230.7 yards, with a standard deviation of 41.8. Set up the null and...
5) According to a website, the average number of dimples in a colf ball is 336 dimples.com sample of golf balls, and my sample has a mean of 335.4 dimples and a standard deviation want to test if the average number of dimples in all golf balls is actually less than the reported run a simulation, and I get a p-value of 0.154. and a standard deviation of 8.3 dimples. I balls is actually less than the reported 336 dimples....
excel will be helpful too - Problem Par, Inc. Par, Inc., is a major manufacturer of golf equipment Management believe share could be increased with the introduction of a cut-resistant, longer-lasting golf ball. There- fore, the research group at Par has been investigating a new golf ball coating designed to resist cuts and provide a more durable ball. The tests with the coating have been promising. Chapter 10 Inference About Means and Proportions with Two Populations One of the researchers...
