Funds A, B, and C each return 15%, while the SP 500 returns 10%. Relative to the SP 500, which fund has the highest alpha?
Fund C, which has a beta of 0.8. With its beta, you'd expect Fund C to gain 8% (10% x 0.8 = 8%). It made almost twice that. Fund A should have gained 10%, so it earns a lower alpha than Fund C. Fund B should have returned 17%, so the fund has a negative alpha.
4.

True. After all, it measures performance relative to beta.
