JET Copies Patrick Prophet Quantitative Methods – MAT 540 Dr. LaTasha Thompson 10/22/10 1. Write a brief description of how you implemented days-to-repair. When looking at the days it took to repair the copier, all that the JET Company had to go by was the average number of days that it took for the company to repair the copier if it broke down. The average was between 1 and 4 days to have the machine repaired. For this data, a probability distribution table was developed and programmed

There are four methods of cerebral lateralization to study the different functionalities of the left and right hemispheres. These methods include the sodium amytal test, the dichotic listening test, and functional brain imaging moreover, the relation between handedness and language lateralization method. In the sodium amytal test, patients’ language abilities are assessed by a neurosurgeon before going into surgery. In the sodium amytal test, sodium amytal is injected into the carotid artery on

different functionalities of the left and right hemispheres. Cerebral lateralization is the process which the two hemispheres of the brain increasingly specialized in particular tasks. There are four methods of cerebral lateralization to study the functions of the right and left hemisphere of the brain. These methods include the sodium amytal test, the dichotic listing test, and functional brain imaging. The forth method of cerebral lateralization is comparing the effects of unilateral left and right
