Sample 9.23 A manufacturer of chocolate candies uses machines to package candies as they move along a filling line. Although the packages are labeled as 8 ounces‚ the company wants the packages to contain a mean of 8.17 ounces so that virtually none of the packages contain less than 8 ounces. A sample of 50 packages is selected periodically‚ and the packaging process is stopped if there is evidence that the mean amount packaged is different from 8.17 ounces. Suppose that in a particular of 50 packages

Computer Science vs. Computer Engineering Moving from High School to college is often a rollercoaster on the mind of most students. After the appliance and acceptance process‚ we then encounter a bigger question: What will our major be? As a computer and technology lover‚ I had a hard time understanding and choosing between computer science and computer engineering; even though I already knew that I wanted to study computers. People often think that studying computer science is the same as studying
