Assume you get a new job as a coach for a sports team, and one of your first decisions is to choose the sports drink that the team will use during practices and games. You obtain a Sports Report magazine so you can use your statistical background to help you make the best decision. The following table lists the most popular sports drinks and some important information about each. Answer the following questions about the table.

1. Would this be considered a small sample?
2. Compute the mean cost per container, and create a \(90 \%\) confidence interval about that mean. Do all the costs per container fall inside the confidence interval? If not, which ones do not?
3. Are there any you would consider outliers?
4. How many degrees of freedom are there?
5. If cost is a major factor influencing your decision, would you consider cost per container or cost per serving?
6 . List which drink you would recommend and why.
