Name: Statistics 1. An investigative reporter contacts a random sample of hotels, and finds a 95% confidence interval for the proportion of hotels in the United States that have reported having bedbugs is (0.04, 0.11). a. Interpret this confidence interval in context. F3 80 b. A national hospitality organization had reported that only 5% of hotels have experienced problems with bedbugs. Does this reporter have compelling evidence that the true proportion is really higher? Explain. c. How could the reporter estimate this proportion with a smaller margin of error? a. Identify the parameter, p, 2. To estimate how often someone runs a red light in Cyber City, a student watched traffic for a while at several randomly selected intersections.
