Hockey sticks: The breaking strength of hockey stick shafts made of two different graphite-kevlar composites yields the following results (in Newtons). Composite 1: 560.4 521.4 554 509.4 507 519.1 536.8 521.5 539.1 Composite 2: 545.9 574.3 533.8 533.3 515.4 549.7 517 511.8 536.4 538.1 568.9 533.6 557.8 Send data to Excel Can you conclude that the standard deviation of the breaking strength Composite 2 is greater? Use the a =0.05 level of significance. State the null and alternate hypotheses. X X H : 1 = 2 X H1 :
