90-day U.S. interest rate	2.20%

Given this information, the yield (percentage return) to a U.S. investor who used covered interest arbitrage would be ____% (assume the investor invests $1 million). The yield (percentage return) to a Canadian investor who used covered interest arbitrage would be ____%.
