3. Assume that you have been testing different programs to reduce the number of times of driving under inference (DUI) among college students. You have presented three different treatment programs to three groups of students, and a fourth group of students served as a control group (no treatment). You then measure the number of times that students of each group driving under inference over a five-month period. There are 6 students in each group. Conduct a statistical test to compare the differences of the number of times committing DUIs between the groups. Use $\alpha = .05$ A. Write down the null and alternative hypotheses using statistical symbols. Explain your symbols (4 points) B. Calculate the degrees of freedom $df_{between}$ and $df_{within}$. Show all calculations (4 points) C. What is the critical value? (1 point) PSYC 2000 Statistics Name D. Below is the ANOVA table. Fill in all the blanks. Show your steps (7 points) Source Sum of Squares df Mean Squares F Test Statistic Between 660 Within Total 1130 F. What is your conclusion? (1 point) G. Report the results in APA style (3 points)

Josh is conducting a study on how much alcohol consumption affects reaction times to a sudden event in a driving simulator. He randomly assigns 6 participants to one of three conditions: control, 1-shot of alcohol, or 3-shots of alcohol and then waits 20 minutes before sending the participant in to the driving simulator. A. Identify any independent and dependent variables. What are the levels of the IV(s)? B. Identify your null and alternative hypotheses, write them out in words only. C. What type of statistical test you will perform? D. Determine your alpha level, tails, and degrees of freedom to find your critical value. E. Conduct your statistical test and report the p-value. Hint: Draw a source table. SSBetween = 120 and SSTotal = 150. F. Interpret your results with stats language. Be sure to make a decision on whether you should reject or retain your null hypothesis. G. Josh believes that the control group will have the fastest reaction times, followed by those with 1-shot of alcohol, and those with 3-shots of alcohol will be the slowest. Can his one-way ANOVA support or refute this theory? Explain.

Text: Instructions Conducting an ANOVA on the data sets Question 1 A researcher interested in the effects of alcohol on fine motor control randomly assigned 36 participants to one of three groups. Participants consumed either 0, 5, or 15 ounces of alcohol. They traced a star while looking at the image of the star in a mirror. The researcher counted the number of errors each participant made while performing the mirror image tracing task. Conduct a one-way ANOVA on the following data to determine if alcohol affected performance. You need to first determine whether the experiment was an independent-measures, correlated-measures, or a mixed-measures design. 0 Ounces 5 Ounces 15 Ounces 5 8 15 1 9 18 0 12 11 2 10 13 Question 2 A social psychologist compared the effects of different types of pick-up lines (Direct: "Hi my name is Taylor, what is yours?" versus Sexual: "I might not be Fred Flintstone, but I can make your bed rock") on participants' ratings of how likely they'd date someone using that line using a 5-point scale (1 very unlikely to 5 very likely). Participants were exposed to one of two types of lines given by either an attractive or unattractive person. Note: this was a completely independent groups design so the five scores in each group below represent 5 participants. Conduct a two-way ANOVA on these data and write your result up in APA style. The ratings given by participants in each condition are shown below: Direct Line Sexual Line Attractive 5 4 5 5 4 3 4 4 5 4 Unattractive 3 2 3 3 1 1 1 2 3 1
