Question

You measured 0.0899 ± .0008 µg/mL, also with 7 samples [0.092, 0.089, 0.097, 0.808, 0.091, 0.082, 0.095] ± 0.002 µg/mL. Use a t-test to determine if levels have changed with 95% certainty. Note: for equal size samples with equal uncertainties, you may use the following formula, where n is the number of samples in one week’s data set. The degrees of freedom in this case are 2n-2. You can look up a t-table.
