Part I: True/False

Alright! Let us start out with something rather easy. Please circle T if the statement is always true and F otherwise.

1. An assumption of the analysis of variance procedure is that the populations have the same variance.

2. The test statistic for the Binomial test has a Binomial distribution.

3. The Wilcoxon test is an alternative to the one-sample t-test.

4. The Fligner-Killeen test can be used to test the null hypothesis 1 = 2.

5. The Bonferroni adjustment should be made whenever one performs multiple tests for a single null hypothesis.

6. The Chi-Square Goodness-of-Fit test is appropriate to test if the means of three groups are equal.

7. The Chi-Square Goodness-of-Fit test is appropriate to test for independence between two categorical variables.

8. The null hypothesis is the opposite of the research hypothesis.

9. The t distribution has one parameter, the number of degrees of freedom.

10. If the sample size is large enough, the Central Limit Theorem states that the distribution of the data is approximately Normal.

1) this statement is false because if we assume the variance to be same then we will not get the correct results

2) this statement is true as for the binomial test the distribution should be binomial distribution as it has only two option success and failure

3) this statement is true as wilcoxon is always and can be used as an alterntative when to one sample t test as its is more precise also

4) this statement is true as fligner test is always used where the null hypothesis states that the mean are equal
