You are conducting a study in which you are comparing approachability and shirt color. You count the number of times someone wearing a black shirt is approached and then count the number of times someone wearing a red shirt is approached in a pub. You collect the following data: Black Red N 7 N 5 4 a 5 W N 4 a. What is the IV? What is the DV? b. What is the null and alternative hypothesis? c. What type of test should be used to analyze these results? d. Alpha is set to .05. What are the df? What is t-critical? e. Conduct the appropriate analysis (Std. error = .648; S-hatDbar / S-hatpooled = 1.03). f. Calculate and interpret d. g. Calculate the confidence interval around the mean difference. h. Interpret the results. Be sure to include all information you have and explain in sentence format.WAITl! You now realize that this data actually came from the same participants on two different visits to the local pub. One time they worse a black shirt and the other time they wore a red shirt. Decide whether this changes the type of study to a different type of t-test. Analyze the data and write a conclusion. Black Red 2 7 2 5 4 6 2 5 3 4 a. What is the IV? What is the DV? b. What is the null and alternative hypothesis? c. What type of test should be used to analyze these results? d. Alpha is set to .05. What are the df? What is t-critical? e. Conduct the appropriate analysis (Std. error = .663; S-hatDlDar / S-hatpooled = 1.48). f. Calculate and interpret d. g. Calculate the condence interval around the mean difference. h.
