Errors in surveying

An error in surveying is defined as the difference between two or more values of an identical quantity. However, the estimates are never accurate and there will always be a degree of variability regardless of the research tool or method used. These differences are known as errors that need to be reduced or eliminated to maintain certain levels of accuracy. Even if you carefully follow the prescribed test procedures, the considerations may contain errors.

6. A line was measured 5 times with a tape on a windy day with these results: 286.85, 286.96, 286.77, 286.80, and 286.88 ft. Find the mean and standard deviation of a single measurement. Then, the measurement was repeated 15 more times, giving a mean of 286.87 ft and a standard deviation of 0.06 ft. Have there been enough repetitions to assure that the standard error of the mean is less than 0.02 ft?
