First calculate the arbitrage-free price of the T-Bill: (Note that the spot rates given are annual yields and that you need to divide them by 2 to get the semiannual yields.)
PV =
20 / (1 + 0,01) +
20 / (1 + 0.0125)^2 +
20 / (1 + 0.015)^3 +
20 / (1 + 0.02)^4 +
1,020 / (1+ 0.03)^5
= 956.78
If the note is currently selling for $976.00 the bond is mispriced by + $19.22.
You could explore this arbitrage opportunity by short-selling the T-Bill and using th e proceeds to purchase strips/ zero coupons equivalent to the T-Bill payment structure. You’ll realize an inmediate risk-free profit of $19.22 as the short-selling liability is offset by the future proceeds of the strips / zero coupons.
