Suppose that a random sample of 128 graduate-admissions personnel was asked what role scores on standardized tests play in consideration of a candidate for graduate school. Of these sample members, 70 answered "very important." Find a 95% confidence interval for the population proportion of graduate admissions personnel with this view. Click the icon to view the standard normal distribution table. The 95% confidence interval is from to (Round to four decimal places as needed.) ...
Samples of two different models of cars were selected, and the actual speed for each car was determined when the speedometer registered 50 mph. The resulting 95% confidence intervals for true mean actual speed were (51.7, 53.1) and (49.6, 50.8). Assuming that the two sample standard deviations are equal, which confidence interval is based on the larger sample size? (51.7, 53.1) or (49.6, 50.8) Explain your reasoning. As the sample size increases, the width of the interval decreases. As the sample size increases, the width of the interval increases.

To determine the views of students on a particular campus about fraternities, an 11-point attitude scale was administered to a random sample of 25 students. This survey yielded a sample mean of 5 (the higher the score, the more favorable the view of the fraternities) and a standard deviation of 1.5. Find the 95% confidence interval for the population mean.
