For the following experiment, state the type of test we should use.Assume homogeneity of variance (where applicable) and the validity of parametric tests (where applicable), unless something is directly stated (e.g., "the data are not at all normal") or otherwise indicated (viz., by the inspection of the data) which would indicate an obvious violation of an assumption.This means you must inspect the data for violations of all assumptions.Assume n is large enough, unless stated.Assume is unknown, unless stated.
