Case Problem: Par‚ Inc. Section I: Summary Par‚ Inc.‚ a major manufacturer of golf equipment believes that a cut-resistant‚ longer lasting golf ball could increase their market share. In addition to the requirement that the ball be longer lasting‚ they wanted to ensure that the new coating would not reduce driving distances‚ and would be comparable to the current product.

The management at Par Inc. believes that with the introduction of a cut-resistant‚ longer-lasting golf ball could increase their market share. A new golf ball coating designed to resist cuts and provide a more durable ball have been developed and tested. A sample of 40 balls of both the new and current models were tested with a mechanical hitting machine so that any difference between the mean distances for the two models could be attributed to a difference in the two models. Therefore‚ the hypothesis

Here is the report about Par‚ Inc.‚ is a major manufacturer of golf equipment test whether the new ball drive longer distance than the current model. To compare the driving distances for the two balls‚ 40 simple tests both of new and current models were subjected to distance tests. According to the data‚ we got the information we need for a hypothesis test as follow: | Current | New | Means | 269.42 | 266.67 | Count | 40 | 40 | Standard Deviation | 8.09 | 9.79

Executive Summary: Par‚ Inc has developed a new coating designed to resist cuts and provide a more durable ball. One concern for Par‚ Inc was the effect of the new coating on driving distances. Par would like the new cut-resistant ball to offer driving distances comparable to those of the current-model golf ball. To compare the driving distances for the two balls‚ 40 balls of both new and current models were subjected to distance test. The testing was performed with a mechanical hitting machine

This report is case study of Par‚ Inc. Par‚ Inc.‚ is a manufacturer of golf equipment. The company wants to check whether this new type of golf ball is comparable to the old ones. Therefore they did a test with 40 samples of both new balls and old ones. The testing was performed with a mechanical hitting machine so that any difference between the mean distances for the two models could be measure to evaluate the difference in the two models‚ presented with the sample size of 40 and confidence level

confidence intervals The confidence intervals represent upper and lower bounds of variation around each reference forecast. Values may occur outside the confidence intervals due to external shocks‚ such as extreme weather‚ structural changes to the economic system‚ geopolitical events‚ or technology development. The confidence intervals increase in width throughout the forecast period due to the increasing level of uncertainty in each subsequent year. The upper and lower bounds were based
