The department head wanted to see how many 18-wheel tractor trailers passed along the road. These estimates will be used to determine road improvement and construction considerations and in road patrol planning. The department head asked researchers to calculate the estimated vehicles at different locations on the inter-island road over the past 7 days. Of the 3,481 vehicles counted, 927 were 18 wheelers. However, out of a total of 927, there were 74 who had accidents, so the sample was calculated based on the results of reducing the number of accidents. Determine the point estimate for the proportion of vehicles traveling on KM 25 during this time period which are 18 wheelers! (Assume the confidence level is 99%). What is the benefit of estimating the estimated value in this case (analyze the answers you have obtained)?
