Post an example of a scenario that would warrant either a one-sample or a two-sample test. This can be a hypothetical example.

Please state H0 and H1 and explain why your hypothetical example qualifies as either a one- or two-sample test. (Please recognize that one- and two-sample tests are not the same as one- or two-tail tests.) Also, clearly state the reason(s) this hypothesis test would be conducted. You do not actually have to complete the hypothesis test steps.
