3. Researchers conducted an experiment on how fast we make snap judgments about the friendliness of people we meet for the first time. The researchers want to know if the judgment time increases (it takes longer) if participants view altered photos of faces with hidden eyes. They have ten participants judge both normal and hidden eyes faces. The data are shown below. Conduct all six steps of hypothesis testing (use p=.01). Be sure to label all six steps. Also, include a concluding statement (which should include the effect size).
