Part 2 N FL Lightweights- Do some teams weigh less than others? The following data are weights (pounds) of a random sample of professional football players from each of the following teams. Is there a difference in the mean weights? Since there are more than 2 populations, use ANOVA to see if we can prove a difference. Answer the following questions: a) Is this an Experimental Design Study or an Observational Study? b) Dene the populations and the population parameters? (Dene each of them!) c) Run ANOVA using Excel. Use alpha = .05 and the p-value to test and see if it can be proven that not all the population means are the same.

Note: Fora demonstration of what I am asking you to do here, see Video 3 "Restaurant Odors " - 9. 1, 9.2. d) If you were able to determine that there was a difference between at least two of the means, use Tu key Condence intervals to do multiple pairwise tests. Do these by hand using the formulas and the "Tukey Table" provided on this week's section 9.3 page in eLearn. -- Note: Fora demonstration of what I am asking you to do here, see the video Applying Tukey's Method for the "Gasoline Types" example. e) What do the Tukey condence intervals tell you? f) Use the "Tu key Condence Interval point estimate" formula (section 9.3 eLearn) to estimate the mean weight of the Forty Niners. Make sure you interpret this condence interval. Note: Fora demonstration of what I am asking you to do here, see video "Gasoline Types" - 9.3 in eLearn. g) What is you r overall conclusion for this experiment
