*. The mean difference is significant at the .05 level.
Your research hypothesis is "In the population, there is a difference in the average income among the following groups: those with less than a high school degree, those with just a high school degree, and those with at least a junior college degree."
A) What is your null hypothesis?
B) Are your sample results consistent with the null hypothesis or the research hypothesis? (null / research)
C) What is the probability of getting the sample results you got if the null hypothesis is true? (If this step in hypothesis testing can be skipped, write the word "SKIP".)
D) What is your conclusion? (In other words, do you "reject" or "not reject" the null hypothesis based on these results?)
E) Are your results statistically significant? (yes / no)
F) Is it appropriate to discuss the results of the post hoc multiple comparisons tests? (yes / no)
G) If it is appropriate to discuss the post hoc multiple comparison tests, which pairs of groups are probably different from one another in the population? If it is not appropriate, explain why it is not appropriate.
