Engineering Standards and Codes

Standards are technical publications designed to ensure the reliability of goods, products, methods, or services. They establish technical requirements, specifications, guidelines, features, or design procedures. Standards recommend a set of tolerance for design, processes, operations, production methods, or equipments used in a particular area. Standards are not legally binding unless they are accepted as code or regulation.

Question

A researcher was observing traffic along one lane of a rural highway. During a 1 minute time interval, ten vehicles were observed travelling 65, 64, 71, 66, 58, 72, 69, 66, 55 and 62 mph. Using these spot speeds, calculate the space mean speed (mph). Provide your answer to the nearest tenth of a mph.
