A hospital has three emergency generators for use in case of a power failure. Each generator functions independently, and the manufacturer claims that the probability that each generator will function properly during a power failure is 0.95. 1. List all of the possible outcomes in the sample space, S, and find the probability associated with each outcome. 2. Define the random variable X = the number of generators that fail. Calculate the value of X for each outcome in the...

Managerial Decision Making Model Short Answer Something's wrong! Generator X Company produces two generators. The Excel has been manufactured for more than 20 years and it sells for $900. The Power is a new model developed and marketed approximately two years ago. It sells for $1,140. Based on the information in the company's income statement for 2020, upper management wants to downscale the spend available marketing dollars on the Power while beginning to phase out the production of the Excel....

One generator is placed in standby redundancy to the main generator. The faliure rate of each generator is estimated to be λ = 0.05/hr. Compute the reliability of the system for 10 hrs and its MTBF assuming that the sensing and switching device is 100% reliable. If the reliability of this device is only 80%, how are the results modified?

Part B Why use tweezers to put disks on the plate? Why sterilize tweezers after each disk is put on the agar? Why spread the bacteria out all over the agar plate? Why put a disk with NO antibiotic on each agar plate? Why put a disk with newly purchased, fresh antibiotic on each plate? Why put so many disks on each plate? Why wait 16-20 hours after you have put the bacteria and antibiotic disks on the plate? Part...
