Statistics can help decide the authorship of literary works. Sonnets by a certain Elizabethan poet are known to contain an average of 8.9 new words. The standard deviation of the number of new words is 2.5. Now a manuscript with six new sonnets has come to light, and scholars are debating whether it is the poet's work. The sonnets contain an average of 10.2 words not used in the poet's known works. Assume the number of new words used by this poet in each poem is normally distributed. What can you say about the authorship?

CPP is interested in comparing if they should maintain the current lighting fixtures in Building 9 that has a life-cycle cost (NPV) of $50,000 or invest in new, indirect lighting fixtures in Building 9. The cost for the new fixture is $12,000 with savings of $1,000/year. A rebate will be granted after two years of operation for $1,500. Study period is 15 years. The university uses an annual rate of return of 4%. Calculate the life-cycle cost (i.e. NPV) for the new fixtures and advise if CPP should change the current fixture to the new ones.

We want to improve program performance by %5, we can increase clock rate but doing so will require 1.25 times as many clock cycles. Calculate the new clock rate? Calculate what the new clock rate needs to be to accomplish this performance improvement. Current CPU Time is 18.8 and clock rate is 3.5 GHz. CPI = 1.4 and Instruction count = 47
My answer is:
New Clock Cycles = 0.357
New Clock Rate = 17.86/47*1.4 = 0.2712
Is my answer correct?
