H3 a : For the 1995 to 2008 periods, there is a significant difference between the mean<br />

Sharpe ratio for the passively managed DAX Index and the actively managed Equity Europe<br />

Morningstar Equity Europe Investment Category for the period January 1, 1995-December 31,<br />

2008 with 730 data points. Appendix B presents a side-by-side comparison <strong>of</strong> the indices’<br />

weekly Sharpe ratios.<br />

Table 5 below shows the F-test two-sample for variances result. The 2.847 F-value for<br />

the Morningstar Europe Investment Category is more than the 1.130 F-critical one-tail value.<br />

The indication is a rejection <strong>of</strong> the null hypothesis because the variances due to the larger F-<br />

value. The 9.72834E-44 p-value is less than the assumed .05 level <strong>of</strong> significance (alpha); an<br />
