complete the following questions in a 1-3 page document formatted per APA Requirements. Be sure to use Version 1 of Online Statistics: An Interactive Multimedia Course of Study:http://onlinestatbook.com/version_1.html The following questions use data from theAngry Moods(AM) case study. 1. Lane, Chapter 7, exercise 25 (Angry Moods Study) 25. Suppose in the population, the Anger-Out score for men is two points higher than it is for women. The population variances for men and women are both 20. Assume the Anger-Out scores for both genders are normally distributed. Given this information about the population parameters: (a) What is the mean of the sampling distribution of the difference between means? (relevant section) (b) What is the standard error of the difference between means? (relevant section) (c) What is the probability that you would have gotten this mean difference (see #24) or less in your sample? (relevant section) 2. Lane, Chapter 8, exercise 25 (Angry Moods Study) (AM#10) Calculate the 95% confidence interval for the difference between the mean Anger-In score for the athletes and non-athletes. What can you conclude? (relevant section) 3. Lane, Chapter 9, exercise 27 (Angry Moods Study) For the following problem (#27) complete the three parts listed below: (a) What is the 95% confidence interval on the difference between means? (relevant section) (b) Based on your confidence interval, can you reject the null hypothesis at the .05 level? (relevant section) (c) What do you conclude? (relevant section&relevant section) 27. (AM#6) Is there a difference in how much males and females use aggressive behavior to improve an angry mood? For the “Anger-Out” scores, compare the means for each gender.
