A surveying instructor sent out six groups of students to measure a distance between two points on the ground. The students came up with the following six different values: 150.52, 150.35, 150.89, 150.02, 150.98 and 150.78. Assuming these values are equally reliable and that variations results from accidental errors, determine the most probable value of the distance measured.

Megan is a recent civil engineering graduate. One of her first job is to calculate a bridge cost using the following data. The first cost will be $49,000, the annual operating costs for energy and maintenance will be $15,000, the expected life in 10 years, the expected salvage value is 0 and the firm's interest rate is 9%.
