2. Dr. Coca, an addiction researcher, has developed a medicine that he hopes will help people with a cocaine addiction stop using cocaine. Lab testing of the medicine began with rats. Many rats were trained to press a lever to receive an injection of cocaine until they were considered "addicted". Then, some rats were given a placebo (no medicine), a second group 1 A of rats was given 1mg of the medicine, and a third group of rats was given 2mg of the medicine. Then, Dr. Coca recorded how many times the rats pressed the lever for cocaine in fifteen mins. Their data are below. Does the drug work? Does dose (1mg or 2mg) matter? Placebo 1mg 2mg M₁ = 6 M₂ = 5 M₁ = 1 ΣΧ’ = 356 n = 5 n = 5 n = 5 G=60 T₁=30 T₂ = 25 T₁ = 5 N = 15 SS₁ = 14 SS₂ = 20 SS, 12 k=3
a. State your hypotheses. b. Calculate the test statistic (show ALL work with appropriate notation - if long decimals are involved, maintain 3 decimals in your formulas). c. Organize your findings in an ANOVA table (round to 3 decimals). d. State your Farit (a=.05). State whether or not you can reject the null. e. If appropriate, conduct post-hoc tests using Tukey's HSD. f. Write a conclusion in APA format that summarizes what you've found. Be sure to mention the medicine, cocaine, lever presses, and the appropriate stats (round to 3 decimals). If you conducted post-hoc tests, summarize those results as well. If you want, you can print this page and use the space below to create your ANOVA table. Provide all appropriate row and column labels. There may be extra space or rows below (1 don't know how many you'll need), so don't worry if there's empty space. Handwritten tables are fine too. Please don't write answers or show work on this page (except in the table)! Use blank paper.
