According to statistics reported on CNBC, a surprising number of motor vehicles are not covered by insurance. Sample results, consistent with the CNBC report, showed 38 of 171 vehicles were not covered by insurance. a. What is the point estimate of the proportion of vehicles not covered by insurance (to 4 decimals)? b. Develop a 90% confidence interval for the population proportion (to 4 decimals). ( . ) A sample survey of 56 discount brokers showed that the mean price charged for a trade of 100 shares at $50 per share was $33.78. The survey is conducted annually. With the historical data available, assume a known population standard deviation of $14. a. Using the sample data, what is the margin of error associated with a 99% confidence interval (to 2 decimals)? $ b. Develop a 99% confidence interval for the mean price charged by discount brokers for a trade of 100 shares at $50 per share (to 2 decimals).
