For this project, you will investigate whether there are differences in the mean sodium content of poultry, beef, and meat hotdogs. The data are available in the file ‘hot dogs.txt".

1. Explain why an Analysis of Variance is appropriate for these data.

2. Create appropriate graphical summaries of the data. Use these summaries to

i. Draw preliminary conclusions about the data - justify your conclusions.

ii. Check the assumptions that underlie ANOVA.

3. Conduct ANOVA to compare the mean sodium content of the different meat content hotdogs.

Report instructions:

The report must be typed and double-spaced; no more than 3 pages including graphics. Include all figures, summaries and computer output used in your analysis.

The write-up will include the following (labeled) sections:

I. Problem Statement
II. Methods
III. Conclusions
IV. Discussion
