use excel to calculate confidence interval

Project Description:

construct a 95% confidence interval for the ratio of the variance of two sets of data. i will provide the data. in excel use separate sheet for each chart, pivot table, or table created with the analysis tool-pak, name each tab with the name of the table or chart, and format numbers to 3 decimal places.

in excel perform calculations as far as possible. then show work and formula used in a word document to show how you got the response.

once the calculations are complete, discuss in the word document the assumptions made for the analysis. also determine at 5% significance level if one set has more variability than the other. i am happy to chat more about the requirements. will need a finished product within three days :)
