The described situation requires inference about a mean or means. Identify the response variable and whether the setting involves a single sample, a matched pairs, or two independent samples.
To check a new analytical method, a chemist obtains a reference specimen of known concentration from the National Institute of Standards and Technology. She then makes 20 measurements of the concentration of this specimen with the new method and checks for bias by comparing the mean result with the known concentration.
