1. Use theSnakes dataset:Snakes.RData. Use R when appropriate. Provide the following for each ANOVA: 1) Assessment of all assumptions(if any fail, move a head with analysis, but note in your conclusion), 2) Hypotheses, 3) Conclusion & Interpretation, and Tukey differences where appropriate. Include all necessaryinformation to address the question(s) asked.

Again, please use a similarclean formatting structureas used in previous Tie it Together assignments from module 4 and 5.

Homework Questions

1. We developed a study to determine if different heart drugs had an effect on pulse rates in snakes. We placed snakes into three groups, and administered one of three drugs. Determine if there is a treatment effect of drug on pulse rate. If there is an effect, determine (if possible) which drug reduced the pulse rate in snakes the most.
2. We also tracked the weight in snakes within the groups described above. Determine if there is a drug effect on weight. If there is an effect, determine (if possible) which drug increased snakes' weight the most.
3. Just to be sure, we also tracked length measurements of the snakes. Determine if there is a drug effect on length. If there is an effect, determine (if possible) which drug leads to the shortest snakes.
