A group of psychologists recently examined the how odor influences emotion between male and female. Three groups of participants (half male, half female) were first subjected to different types of smell (pleasant, neutral, and unpleasant), and then filled out questionnaire of happiness. The data present the pattern of results obtained in the study, with higher scores indicating a higher level of happiness Odor pleasant neutral unpleasant Male n = 5 n = 5 n = 5 M = 8 M = 7 M = 0 SS = 6 SS = 5 SS = 4 Female n = 5 n = 5 n = 5 M = 7 M =2 M = 0 SS = 6 SS = 4 SS = 6 Note: grand mean =4 A) Conduct a hypotheses testing with α = .05 to evaluate the main effects and interactions (follow the four-step procedure).

A)
Conduct a hypotheses testing with α = .05 to evaluate the main effects and interactions (follow the four-step procedure).
B)
Calculate the effect size (partial η2) for the main effects and the interaction.
C)
Plot the cell means in a graph, with odor type on the x-axis.
D)
Based on the pattern of interaction shown in the graph, briefly explain how gender and odor condition influence the happiness according to this pattern of results.
