1. Based on the histograms given below would you assume the data are distributed normally? Explain.
2. Using the results from the proc univariate give the sample sizes, means, and standard deviations for the three drug levels.
3. Using the output from proc glm on page 17 complete a hypothesis test for mean differences. Give all 4 steps.
4. If you found a significant difference between means in c then look at the output associated with contrasts on pages 18-24 and indicate which means are different. Note. Assume that you didn’t specify any a priori tests prior to conducting the experiment.
5. Using page 16-24 and knowing that you didn’t specify any a priori tests prior to running the experiment which method would not be appropriate for determining whether the means are different?
