Suppose that a safety group surveyed 1,200 drivers. Among those surveyed,78% said that careless or aggressive driving was the biggest threat on the road, and 33% said that cell phone usage by other drivers was the driving behavior that annoyed them the most. Based on these data and assuming that the sample was a simple random sample, construct and interpret a 99% confidence interval estimate for the true proportion in the population of all drivers who are annoyed by cell phone users. The confidence interval estimate is _____ to _____. (Round to three decimal places as needed. Use ascending order.)
An auditor of the USPS wants to examine its special two day mail handling to determine the proportion of parcels that actually arrive within the promised two day period. A randomly selected sample of 1600 such parcels is found to contain 1250 that were delivered on time. Use this to construct a 95% confidence interval for the parcels delivered on time.
Suppose that a random sample of 142 graduate-admissions personnel was asked what role scores on standardized tests (such as the GMAT or GRE) play in the consideration of a candidate for graduate school. Of these sample members, 87 answered “very important.” Find a 95% confidence interval for the population proportion of graduate admissions personnel with this view.
