The university has in store a large number of used computers. It is known that 51% of these computers have 500 GB hard disks, 40% of the computers have 4 GB RAM and 10% have a 500 GB hard disk and a 4 GB RAM. A computer is chosen at random from the university store.

  1. What is the probability that it has a 4 GB RAM but not 500 GB hard disk?
  2. What is the probability that it has neither a 4 GB RAM nor a 500 GB hard disk?

    You have two Windows Server 2012 R2 computers with the Hyper-V role installed. Both computers have two hard drives, one for the system volume and the other for data. One server, named HyperVTest, is going to be used mainly for testing and what-if scenarios, and its data drive is 250 GB. You estimate that you might have 8 or 10 VMs configured on HyperVTest with two or three running at the same time. Each test VM has disk requirements ranging...

    A university computer lab has 128 computers, which are used continuously from time of installation until they break. The average time to failure for these 128 computers was 1.523 years. Assume this information is a summary of a random sample from an exponential distribution. Construct an approximate 95% confidence interval for the parameter ?. (Hint: Use the large sample form for the confidence interval.)

    answer neatly and correctly please! The university data center has two main computers. The center wants to examine whether computer 1 is receiving tasks that require processing times comparable to those of computer 2. A random sample of 12 processing times from computer 1 showed a mean of 62 seconds with a standard deviation of 17 seconds, while a random sample of 9 processing times from computer 2 (chosen independently of those for computer 1) showed a mean of 66...
