O 1) ( 7.528 , 8.78 ) O 2) ( 7.007 , 9.301 ) ( 3) (-7.007 , 9.301 ) (4) (7.02 , 9.288) O 5) ( 6.321 , 9.987 )Suppose you are a civil engineer, specializing in traffic volume control for the City of Grand Rapids. Your department has been receiving a multitude of complaints about trafc wait times for a certain intersection in the heart of downtown. To see if these claims are valid, you want to monitor the true average wait time at that intersection. Over the course of a few months, you record the average number of minutes a car waits at the intersection between 4:00 PM and 5:00 PM. With a sample size of 10 cars, the average wait time is 8.154 minutes with a standard deviation of 1.9785 minutes. Construct a 90% confidence interval for the true average wait time for a car at the intersection between 4:00 PM and 5:00 PM
