Professor Ahmad of Oasis University gave an engineering case study to his class to analyze and comment. It is a famous case that many universities use in engineering education. Omar, who is a student of Professor Ahmad's class found a website that contains analysis done by many students of Western University. Omar told his close friends Jameel and Khalid what he found. They selected three different analyses. That means each one got a well- written and ready-made answer. Omar directly copied from what he selected. He did not even indicate the website as a source of reference in his submission. Jameel did not directly copy from the one he selected. He rephrased some of the sentences. He also indicated the website as a source of reference in his submission. Although Khalid studied the sample he selected and some others samples available on that website, he wrote the analysis on his own. He also indicated the website as a source of reference. Professor Ahmad's action is academically Select…

Deborah Kellogg buys Breathalyzer test sets for the Denver Police Department. The quality of the test sets from her two suppliers is indicated in the following table: percent defective probability for winter park probability for technology dayton enterprise 1% 0.65 0.25 3% 0.25 0.25 5% 0.10 0.50 For example the probability of getting a batch of tests that are 1% defective from Winter park technology is 0.65. Because Kellogg orders 10,000 tests per order, this would mean there is a 0.65 probability of getting 100 defective tests out of the 10,000 tests if Winter park technology is used to fill the order. A defectice breathalyzer test can be repaired for $0.50. Although the quality of the…
