###### The Student's t equation can be rearranged to estimate the number of samples that must be analyzed by a specific technique to determine the mean with a desired confidence,t283where n is the number of samples needed, 8s is the sampling standard deviation, t is the Students t value at the desired confidence interval, and e is the sought for uncertainty: This equation assumes that the analytical uncertainty is negligible compared to the sampling uncertainty: Soil samples from a local dog park

The Student's t equation can be rearranged to estimate the number of samples that must be analyzed by a specific technique to determine the mean with a desired confidence, t283 where n is the number of samples needed, 8s is the sampling standard deviation, t is the Students t value at the desired confidence interval, and e is the sought for uncertainty: This equation assumes that the analytical uncertainty is negligible compared to the sampling uncertainty: Soil samples from a local dog park are being analyzed for nitrate content: The sampling standard deviation is known to be +8.0%. Estimate the number of samples that need to be analyzed to give a 98% confidence that the mean is known t0 within #5.0%. Assume the analytical uncertainty is much smaller than the sampling uncertainty Use the Student's t values in this table
