What is the CPI achieved by a 2-issue static superscalar processor on this program?

In this exercise, we make several assumptions. First, we assume that an N-issue superscalar processor can execute any N instructions in the same cycle, regardless of their types. Second, we assume that every instruction is independently chosen, without regard for the instruction that precedes or follows it. Third, we assume that there are no stalls due to data dependences, that no delay slots are used, and that branches execute in the EX stage of the pipeline. Finally, we assume that instructions executed in the program are distributed as follows:
