Compute confidence intervals and what does this tell


Samples of our students from an applied experimental design class were polled regarding the number of hours they spent studying for the last exam. All students anonymously submitted the number of hours on a 3x5 card. There were 24 individuals in the section of the course polled. The data was used to make inferences regarding students taking other sections of the same course. Below is the data:

4.5 22 7.0 14.5 9.0 9.0 3.5 8.0 11.0 7.5 18.0 20.0
7.5 9.0 10.5 15.0 19.0 2.5 5.0 9.0 8.5 14.0 20.0 8.0

Compute 95% confidence intervals. What does this tell us?
