Margin of Error (as a percentage): Confidence Interval: % to % Find the margin of error and confidence interval for the percentage of U.S. adults who regularly use Facebook as a news source, at the 99% level of confidence. Round all answers to 2 decimal places. Margin of Error (as a percentage): Confidence Interval: % to % The more error we allow, the less precise our estimate. Therefore, as the confidence level increases, the precision of our…
A doctor wants to know if his practice provides adequate patient service. He takes a random sample of 50 patients and asks them, "Are you satisfied with the level of care you receive here?".
The data for this exercise was obtained from https://www.currentresults.com/Weather/Florida/yearly-florida-rainfall.php 2 . Tourists often hear about the wonderful, warm Florida weather; they live in blissful ignorance of the freezes experienced in the northern parts of the state. A tourism organization wants to open up the entire state to tourists. They know that not everyone is drawn to hot, sunny beaches, so they want to advertise the advantages of visiting other parts of the state. One of the first things they need to do is educate potential tourists about the weather. And part of that involves informing them about the average rainfall across the state. Your task is to help the tourism organization figure out what the average rainfall in Florida is like. Rainfall data is provided below. The table below gives the typical yearly rainfall in some parts of Florida. Place Rainfall (inches per year) Monticello 56.8 Niceville 71.0 Tampa 46.3 Lakeland 54.8 St. Augustine Lake City 49.0 52.6…
