A program executes 12,000 instructions over its runtime, 13% of which are conditional branches, 5% are unconditional branches. On this processor model, a mispredicted branch has a penalty of 2 cycles, it assumes "always-taken" for unconditional branches, and has a conditional branch prediction accuracy of 70%. What is the CPI without branch prediction? Assume each instruction takes 1 cycle at the baseline, and answer to 2 decimal places.
