- The highway department wants to estimate the proportion of vehicles on a Highway at KM 25 between midnight and 5:00 A.M. The head of the department wants to see how many 18-wheel tractor trailers pass on the road. These estimates will be used to determine highway repairs and construction considerations and in highway patrol planning. The department chief asked investigators to calculate estimates of vehicles at different locations on inter-island roads over the past 7 days. From 3,481 vehicles counted there are 927 are 18-wheel drive. However, out of the total 927, there were 51 vehicles that had accidents so that the sample was calculated based on the results of a reduction in the number of accidents. Specify an approximate point for the proportion of vehicles performingtravel on KM 25 during this time period which is an 18-wheeled vehicle!(Assume the confidence level is 99%). What are the benefits of estimating value estimates in this case (analysis of the answers you have obtained)?In March 2015, Laclede Gas had the following rate schedule for natural gas usage in single-family residences.Monthly service charge $19.50Delivery chargeFirst 30 therms $0.91686/thermOver 30 therms $0Natural gas costFirst 30 therms $0.348/thermOver 30 therms $0.5922/therm(a) What is the charge for using 20 therms in a month?(b) What is the charge for using 150 therms in a month?(c) Develop a function that models the monthly charge C for x therms of gas.(d) Graph the function found in part (c).Identify if the quantity reported is a Parameter or a Statistic 6.
