To be Submitted

A random sample of 100 high school students in CT is taken. The dataset is in the file Backpack.xls. **Do not print out the data file!**

1. **Find and label** the mean, standard deviation, median, minimum and maximum of the variable Backpack weight.

2. **Find and label** the sample proportion of Backpack weights that are between 10 and 20 pounds (include the endpoints).

3. **Find and interpret** a 95% confidence interval for the mean Backpack weight for all CT high school students.

4. Report the error bound.

5. **Find and interpret** a 95% confidence interval for the proportion of all CT high school Backpack weights that are between 10 and 20 pounds.

6. Report the error bound.

7. A researcher claims that the mean weight for all CT high school backpack weights is more than 12 pounds. Using your answer to #3, comment on this claim and justify.

8. A researcher claims that the proportion of all CT high school backpack weights between 10 and 20 pounds is more than 45%. Using your answer to #5, comment on this claim and justify.
