Several years ago, a large state university conducted a survey of undergraduate students regarding their use of computers. The results of the survey are contained in the data file ComputerUse.

a. Based on the data from the survey, what was the probability that undergraduate students at this university will have a major that requires them to use a computer on a daily basis?

b. Based on the data from this survey, if a student was a business major, what was the probability of the student believing that the computer lab facilities are very adequate?

c. Select a sample of 20 students at your university and ask them what their major is and whether the major requires them to access the Internet for computational purposes, with a personal computer, notebook, tablet, or other device. Use these data to calculate the probability of each major requiring a computing device, and then compare your results with those from the older survey.
