Answer #1

1) Answer: B) independent samples t-test

Explanation: The independent sample t test used to test significant difference between two independent groups. Here tenured faculty members and non-tenured faculty members are two independent groups. Hence independent samples t-test is appropriate

2) Answer: D) dependent samples t-test

Explanation: The dependent sample t test used to test significant difference between two dependent groups. Here married women and their husbands are two dependent groups. Hence dependent samples t-test is appropriate

For the following experiment/question, pick the most appropriate statistical test. You have the following statistical tests as choices: some may be used more than once, others not at all.  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 a strong and obvious violation of an assumption. This means you must...
