Assume that the execution time for a program is directly proportional to instruction access time. The access to an instruction in the cache is 10 times faster than access to an instruction in the main memory. If an instruction is not found in the cache, i.e., cache miss, it is fetched from the main memory to the cache and then fetched from the cache to be executed. Assume that a requested instruction will cause cache miss has a probability of 0.08. Let the speedup factor is defined as the ratio of program execution time without the cache to program execution time with the cache.a. Calculate the speedup factor to execute such a program.b. using this assumption, assuming that the cache is 20 times faster than the main memory.

In its 2016 Auto Reliability Survey, Consumer Reports asked subscribers to report their maintenance and repair costs. Most individuals are aware of the fact that the average annual repair cost for an automobile depends on the age of the automobile. A researcher is interested in finding out whether the variance of the annual repair costs also increases with the age of the automobile. A sample of 26 automobiles 4 years old showed a sample standard deviation for annual repair costs of $170 and a sample of 25 automobiles 2 years old showed a sample standard deviation for annual repair costs of $ 100a. State the null and alternative versions of the research hypothesis that the variance in annual repair costs is larger for the older automobiles.b. At a .01 level of significance, what is your conclusion? What is the p-value? Discuss the reasonableness of your findings.

Strains of petunias come in four pure-breeding colors: white, blue, red, and purple. White petunias are produced when plants synthesize no flower pigment. Blue petunias and red petunias are produced when plants synthesize blue or red pigment only. Purple petunias are produced in plants that synthesize both red and blue pigment.The mixture of red and blue makes purple. Flower-color pigments are synthesized by gene action in two separate pigment-producing biochemical pathways. Pathway I contains gene A that produces an enzyme to catalyze conversion of a colorless pigment designated White 1 to blue pigment. In Pathway II, the enzymatic product of gene B converts the colorless pigment designated White 2 to red pigment. The two genes assort independently.Part A: What are the possible genotype(s) for pure-breeding red petunias?AABBAABbAabbAaBbaaBBAAbbaabbaaBbAaBBPart B: What are the possible genotype(s) for true-breeding blue petunias?aaBBAABBAaBBaaBbAAbbAabbaabbAABbAaBb
