Need help with this. not sure if it's right.

Marvin is interested in whether blonds, brunets, and redheads differ with respect to their extrovertedness. He randomly samples 18 men from his local college campus: 6 blonds, 6 brunets, and 6 redheads. He then administers a measure of social extroversion to each individual.

1. Conduct a one-way ANOVA to investigate the relationship between hair color and social

extroversion. Be sure to conduct appropriate post hoc tests. On the output, identify the following:

a. F ratio for the group effect

b.. Sums of squares for the hair color effect

c. mean for redheads

d. p value for the hair color effect

2. What is the effect size for the relationship between hair color and extroversion?

Having F (2,15) = 3.511, p-value 0.056 > 0.05, then the null hypothesis is not rejected. In conclusion, there is no difference among the effects of hair color on extroversion. Since there is no significant difference, a post hoc test could not be conducted.
