Solve the following manually following the steps in hypothesis testing. Do the same using SPSS or any other software, state the null and alternative hypotheses and make a decision and conclusion.
A sporting goods manufacturing company wanted to compare the distance traveled by golf balls produced using two 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 20 balls were hit in a short period of time, during which the environmental conditions were essentially the same. The results (distance traveled in yards) for the two designs are shown in the following table.At the 0.05 level of significance, is there evidence of a difference in the mean distances traveled by the golf balls with different designs?Do
