Suppose that a safety group surveyed 800 drivers. Among those​ surveyed, 83​% said that careless or aggressive driving was the biggest threat on the​ road, and 34​% 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 95​% 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 ??––––––?? ​(Round to three decimal places as needed. Use ascending​ order.) Interpret the confidence interval estimate.     A. There is a 0.95 probability that the population proportion of drivers who are annoyed by cell phone users is in the interval.   B. There is 95​% confidence that the population proportion of drivers who are annoyed by cell phone users is in the interval.   C. There is a 0.95 probability that the sample proportion of drivers who are annoyed by cell phone users is in the interval.   D. There is 95​% confidence that the population proportion of drivers who are annoyed by cell phone users is equal to one of the bounds of the interval.

Average

In mathematics, everyone must have heard the term average in one place or other. Almost all types of calculation require taking out an average. In everyday life, the term is used for denoting a certain amount that can be said to be a typical quantity for multiple people or objects. In other words, if a group of people possesses a certain object, then the average gives us an idea regarding the quantity of the object possessed by each person. However, this is solely based on mathematical calculation. It is important to note that most people will not strictly have the average value in a group.
