1. The activities director of a large university has surveyed a simple random sample of 100 students for the purpose of determining approximately how many students to expect at next month's awards ceremony to be held in the gymnasium. Forty of the students said they plan to attend. What are the upper and lower 95% confidence limits for the number of the university's 10,000 students who plan to attend the awards ceremony?

2. A research firm has found that 39% of U.S. adults in the over-$75,000 income category work at least 51 hours per week. Assuming this was a simple random sample of 500 adults in this income group, construct and interpret the 95% and 99% confidence intervals for the proportion who work at least 51 hours per week. For each of the confidence intervals, identify and explain the maximum likely error in the study.
