Question 5: The highway department wants to estimate the proportion of vehicles on the interstate 605 between the hours of midnight and 5 AM that are 18 - wheel trailers. The estimate will be used to determine highway repair and construction considerations. Suppose researchers for the highway department counted vehicles at different locations on the interstate for several nights during this time period. Of the 3481 vehicles counted, 1027 were 18 - wheelers. construct a 95% confidence interval for the proportion of vehicles traveling the interstate 605 during this time period that are 18 - wheelers.
