A Better Golf Tee? An independent golf equipment testing facility compared the difference in the performance of golf balls hit off a brush tee to those hit off a 4 yards more tee. A‘Air Force One DFX driver’ with 10.5 degrees of loft was used for the test, and a robot swung the club head at approximately 92 miles per hour. Data on ball velocity (in miles per hour) with each type of tee are as follows.

Brush tee 4 Yards More tee x¯1 = 129.24 x¯2 = 129.93 s1 = 0.10 s2 = 0.56 n1 = 30 n2 = 30 At the 1% significance level, do the data provide sufficient evidence to conclude that the standard deviation of velocity is less with the Brush tee than with the 4 Yards More tee? (Note: For df = (29, 29), F0.01 = 2.42.)
