Par Inc Written Report

Case Problem Par, Inc. Par, Inc. is a major manufacturer of golf equipment and they want to introduce a cut-resistant and longer lasting golf ball. Though, the result of test o n the durability of the improved product another issue has been raised – raised – and this is the effect of the new coating on driving distances. 40 balls of both the new and current models were subjected to distance test. Our hypothesis test is Ho: µ1 - µ2 = 0, against Ha: µ1 - µ2 ≠ 0. Just by looking at the descriptive statistics for each model, we can initially conclude conclude that Current model has a longer range of distance based on the 40 samples with a me an of 270.275 compare to 267.500 for new model. To test further our hypothesis, we set our α at .05 and our re jection criteria is Reject Ho and accept Ha if F > Fc or P < α (.05). Since our hypothesis test done thru stat tools doesn’t indicate Fc, we will use the P-value approach. And based on the p-value of 0.0940, we cannot reject Ho, there is no significant evidence that New and current mo del driving distances are different. And to support our hypothesis test, we also perform interval confidence confidence for both model. There is 95% probability that the true population mean is between 267.47 and 273.07 (current model) while 264.33 and 270.66. And by their confidence intervals, we can say that there is no significance difference between the driving distances of Current Model and New Model. And also be cause of this, larger sample size is not anymore required as it will also generate same conclusion. Our recommendation is for the company (Par, Inc.) to continue with further study of t he improved cutresistant, longer lasting golf ball. But ofcourse, Par, Inc. should also consider other factors like costing, availability of suppliers and the like before finalizing and launching the product.
