a. reanalyze because such values are not possible;
b. retain the null hypothesis;
c.reject the null hypothesis and examine the means in order to draw a conclusion;
d. none of the other alternatives are correct

2. An F value obtained from the data is 3.65 based on 2 and 18 degrees of freedom. Alpha = .05. With such results, it is possible to make a ____ error.

b. Type II;
c. both of the descriptive alternatives are correct;
d. neither of the descriptive alternatives is correct.

3. Tukey Honestly Significant Difference test is a(n) ____ test.

c. both of the descriptive alternatives are correct;

d. neither of the descriptive alternatives is correct.

Explanation / Answer

1) In case of F value less than 1, Big bird should retain the null hypothesis.

Option B is correct.

2) Critical value for 2 and 18 degrees of freedom with 0.05 significance level = 3.555

Since the calculated F is greater than this value, we will reject the null hypothesis and hence, scope of Type I error would be there.

Option A is correct.

3) Tukey Honestly Significant Difference test is a post hoc test.

Option B is correct.
