Question
ONLY NEED HELP WITH E AND F PLEASE.
Application Exercise:
A team of comparative psychologists are interested in the maternal behavior or rats. In an experiment, 5, 15, and 30 day-old rat pups were separated from their mothers. They then recorded the time (in seconds) required for the mother rats to retrieve the pups. The psychologists were interest in whether retrieval time varies with age. The data are given below. What can be concluded with ? = 0.05?
a) What is the appropriate test statistic?
---Select--- na one-way ANOVA within-subjects ANOVA two-way ANOVA
b) Compute the appropriate test statistic(s) to make a decision about H0.
critical value = ; test statistic =
Decision: ---Select--- Reject H0 Fail to reject H0
c) Compute the corresponding effect size(s) and indicate magnitude(s).
?2 = ; ---Select--- na trivial effect small effect medium effect large effect
d) Make an interpretation based on the results.
At least one of the rat pup ages differed on the mother retrieval time.None of the rat pup ages differed on the mother retrieval time.
e) Conduct Tukey's Post Hoc Test for the following comparisons:
1 vs. 3: difference = ; significant: ---Select--- Yes No
2 vs. 3: difference = ; significant: ---Select--- Yes No
f) Conduct Scheffe's Post Hoc Test for the following comparisons:
2 vs. 3: test statistic = ; significant: ---Select--- Yes No
1 vs. 3: test statistic = ; significant: ---Select--- Yes No

Explanation / Answer
a. The appropriate test statistic is the one-way ANOVA.
b. critical value = < 0.05; test statistic = F = 7.57348. Decision: Reject H0.
c. effect size = 0.5024; Medium effect size.
d. Interpretation: At leat one of the rat pup ages differed on the mother retrieval time.
