Question
To compare the driving distances for the two balls, 40 balls of both the new and current models were subjected to distance tests. The testing was performed 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.
  • Managerial Report
    Prepare a managerial report that investigates the effect of the new coating on driving distances of golf balls by comparing driving distances for the two models.
     
    Consider the results of the tests, with distances measured to the nearest yard, in the complete data set.
