Question

What type of test it is ?

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 o is unknown, unless stated.
An elementary school teacher wants to know if more boys are likely to speak out in class or
whether girls are more likely to speak out in class. At his school, he notes if each student speaks
out or not.
