Given

Choosing between two proposed traffic safety project intersection of a high crash rate intersection. Two solutions are proposed.

Project A: build a 5.57 million dollars overpass to separate the two roadways. The estimated value of the crash avoided will be 513000 per year over the next 20 years.

Project B: improve the geometry and signal timing at the intersection at a cost of 418000 dollars. The estimated value of the crash avoided will be 61800 dollars per year over the next 20 years.

Required:

A- What is the percent worth benefits and costs (PWB and PWC) for each project? Show cash flow diagrams and calculations. The current interest rate is 5.4% per year.

B- Using Net Present Worth NPW which project is better?

C-Using the benefit cost ratio BCR which project is better?

Tests of Child Booster Seats The National Highway Traffic Safety Administration conducted crash tests of child booster seats for cars. Listed below are results from those tests, with the measurements given in HIC (standard head injury condition units). The safety requirement is that the HIC measurement should be less than 1000 HIC. Use a 0.01 significance level to test the claim that the sample is from a population with a mean less than 1000 HIC. Write the hypothesis find test...
