Final answer:
The statement 'To capitalize on high foreign interest rates using covered interest arbitrage, a U.S. investor would convert dollars to the foreign currency, invest in the foreign country, and simultaneously sell the foreign currency forward' is not true.
Step-by-step explanation:
The statement a.
