I very much need assistance with answering part 2 of this question:
3. Figure 1.19 (page 47) shows the execution time and SPECRatio of 12 SPEC2006 integer benchmarks for the AMD A10 and Intel Xeon E5-2690. (1) If the weights of applications perlbench, bzip2, and libquantum are 0.4, 0.25, and 0.35, respectively. What's the weighted arithmetic mean of execution time on each processor? What's the speedup of Intel Xeon E5-2690 over AMD A10? (2) Using AMD A10 as the reference machine, what's the normalized execution time of the three applications on these two processors? What's the geometric mean of normalized execution time on each processor? What's the speedup of Intel Xeon E5-2690 over AMD A10 using the normalized execution time?

The final two columns show the ratios of execution times and SPEC ratios. This figure demonstrates the irrelevance of the reference computer in relative performance. The ratio of the execution times is identical to the ratio of the SPEC ratios, and the ratio of the geometric means (63.7231.91/20.86=2.00) is identical to the geometric mean of the ratios (2.00). Section 1.11 discusses libquantum, whose performance is orders of magnitude higher than the other SPEC benchmarks. 3.
