A developmental psychologist placed children in a social situation in which they were either rewarded or punished (Factor A: consequence) by a parent, sibling, or stranger (Factor B: type of adult). Following this social situation, children were placed back in the same social situation, and the time it took them (in seconds) to engage in the punished or rewarded behavior was recorded. The data is below:

	Parent	Sibling	Stranger
Reward	15	22	14
	16	16	15
	14	19	18
	13	14	23
Punishment	45	41	25
	43	38	29
	46	49	32
	50	52	39

1. Write the null hypotheses in words. Write the alternative hypotheses in words. Use excel to obtain the test statistics and p-values. Report the two-way ANOVA table.
2. Make a decision about each null hypotheses using the p-value approach. Write conclusion in APA style.
3. Use excel to create an interaction plot. Give a brief interpretation in context of the variables.
