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 back pack 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 back pack weights between
10 and 20 pounds is more than 45%. Using your answer to #4, comment on this daim
and justify.
9. Find and label the mean, standard deviation, median, minimum and maximum of the
variable Body weight.
10. Find and interpret a 95% confidence interval for the mean Body weight for all CT high
school students.
