4. Researchers believe that men are more physically aggressive than women. To test this, researchers ask 20 participants (10 male, 10 female) to rate how aggressive they are on a scale from 1 to 10. Their scores are listed below. Conduct all six steps of hypothesis testing (use p=.05). Be sure to label all six steps. Also, include a concluding statement (which should include the effect size).

2. The steps of hypothesis testing You intend to draw a random sample in order to test a hypothesis about an unknown population mean. You will use a hypothesis test. A description of each of the steps of a hypothesis test follows, but they may be specified in the incorrect order. Specify the correct order of the steps. Determine the null and alternative hypotheses. Select a level of significance. Make a decision about the unknown population. Select a sample and compute the z-score for the sample mean.
A) What is the alternative hypothesis? a. The population mean is equal to 7.2 points. b. The population mean is greater than 7.2 points. c. The population mean is smaller than 7.2 points. B) What Z-score(s) corresponds to the alpha level? In other words, at what point(s) would we reject the null hypothesis? C) What is the test statistic?
