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. a z-test for the difference between proportions a one-sample z test for means a chi-squared goodness-of-fit test a one sample z-test for proportions none of the other tests an independent samples t-test with heterogeneity of variance an independent samples t-test with homogeneity of variance a one-sample t-test for means O a related samples t-test O ooo o o
