4. A six-lane freeway (three lanes in each direction) operates at capacity during peak hour. It has 11-ft lanes, 4-ft right shoulders, and there are three ramps within three miles upstream of the segment midpoint and four ramps within three miles downstream of the segment midpoint. The freeway has an AADT of 60,000 veh/day. The traffic stream has 8% heavy vehicles, and it is on rolling terrain with a peak- hour factor of 0.85. It is known that 12% of the AADT occurs in the peak hour and that the directional factor is 0.6. What is the freeway’s LOS?

Your small remodeling business has two work vehicles. One is a small passenger car used for job-site visits and for other general business purposes. The other is a heavy truck used to haul equipment. The car gets 25 miles per gallon (mpg). The truck gets 10 mpg. You want to improve gas mileage to save money, and you have enough money to upgrade one vehicle. The upgrade cost will be the same for both vehicles. An upgraded car will get 40 mpg; an upgraded truck will get 12.5 mpg. The cost of gasoline is $3.35 per gallon.

Calculate the annual fuel savings, in gallons, for the truck and car assuming both vehicles are driven 8,500 miles per year. (Round your answers to 2 decimal places, e.g., 32.16.)

Assuming an upgrade is a good idea in the first place, which one should you upgrade? Both vehicles are driven 8,500 miles per year. Truck or Car

Storm Delivery Company purchased a new delivery truck for $53,400 on April 1, 2016. The truck is expected to have a service life of 5 years or 150,000 miles and a residual value of $4,320. The truck was driven 8,200 miles in 2016 and 11,800 miles in 2017. Storm computes depreciation to the nearest whole month.

1. A certain town has 9,000 families.Population average mileage driven per family is 15,000 miles per year and the population SD is 2,000 miles per year. Fifteen percent of these families have no cars at all. As part of an opinion survey, a simple random sample of 900 families (from this town) is chosen. What is the chance that sample average mileage driven per family is between 14,950 and 15,100 miles per year? Use the normal approximation method with continuity correction.

2. Somebody picks one ticket at random from a normal population (sample size is equal to 1). The ticket shows a “2”, i.e. the sample average is “2”. Assuming that the SD of the box is 3, determine the 95% confidence interval for the average of the box. (Remark: You should be able to construct a z or t confidence interval.)

3. Determine a 99% confidence interval for the population average of a normal distribution, given a random sample of size 12 with sample average = 2 and sample SD = 3.

On January 1, Year 1, Rex Carr’s Driving School, Inc., purchased $550,000 of vehicles (Equipment) with an estimated useful life of 10 years or 100,000 miles and a $50,000 salvage value. The vehicles were driven 20,000 miles in Year 1 and 30,000 miles in Year 2.
