Consider the following comparison of overall performance of machines A and B across various applications I, II and ill. Machine A" column shows the execution times of Machine A for applications I, I, and. "Machine B" column shows the execution times of Machine B for applications I, Il, and III. "SPEEDUP" column shows the speedups of Machine A over Machine B for applications I, I, and Machine A Execution Times 9 sec Machine B Execution Times SPEEDUP Application I Application II Application IlI Average 7 sec 11 sec 0.7 5 sec a) Fll out the missing numbers in the table. b) To calculate the average speedup across multiple applications, should we: i. Calculate the average speedup by simply averaging all individual speedups for each application? ii. Calculate average speedup based on the average execution times of the two machines? iii. Both yield same answer? c) If methods i and ii are different, when do they yield same
