Question

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 inspect the data
for violations of all assumptions. Unless it is stated that the
population parameter is known, assume it isn’t. Please do not
concern yourself with any intervening variable that you may
perceive. Finally, please don’t think about what the data would
look like in reality. Assume that the question represents
reality. **Please simply write the letter for the
test as your answer. [You can, but need not, add an explanation.]
If none of the tests are appropriate, the answer is P) none of the
above. Here are the tests: **A:** one
sample z-test **B:** one-sample
t-test **C:** t-test for the difference
between means for two related
samples **D:** t-test for the difference
between means for two independent samples with homogeneity of
variance **E:** t-test for the difference
between means for two independent samples with heterogeneity of
variance **F:** a one sample z-test
for proportions (or a chi-square goodness of
fit) **G: **chi-square
goodness of fit only (where a one sample z-test of proportions
isn’t appropriate) **H:** a two-sample z-test for the
difference between proportions (or a chi-square test of
independence) **I: **chi-square test of
independence only (where a two-sample z-test for the difference
between proportions isn’t
appropriate.) **J: **simple
regression **K**:
multiple regression **L: **one-way ANOVA
**M:** two-way ANOVA **N:** Mann-Whitney
**O: **Wilcoxon **P:** none of
the above.

In the United States, ten percent of the population has blond hair. We want to see if the population of Greenland is also ten percent. What test does she use?

1A. the most appropriate t-test if you are comparing means for
two separate groups that have no relationship to each other?
paired samples t-test
independent samples t-test
dependent samples t-test
none of the above
Which of the following tests are necessary to find out the
details of ANOVA?
Chi-Square
correlation
regression
post hoc test

For each hypothesis, the specific statistical test appropriate
for testing the hypothesis should be described and a brief
description of why the chosen test is most appropriate should be
included.
One Sample t-test, Two sample t-test, Two related
(correlated/paired/dependent)sample t-test, One Factor (one way)
analysis of variance (ANOVA), Factorial for two way/facot Analysis
of Variance (Anova), One Variable Chi-Square test, two variable chi
square test, correlation, or linear regression
