For this project you need to run a test of means at 5% significance. Find a set of data that you

them to recent numbers. Use the recent numbers as the sample. You can do the same thing for

state by state numbers. Look at education rates from 20 years ago and then run a test to see if

current numbers are different.

1)Write an intro statement explaining what you are doing, state your significance level

and include Ho and Ha.

2) Explain how you made sure your data was independent in your sample

1) Explain how you made sure your sample was random.

2) Explain the less than 10% condition as well as create a histogram to show that your data

3) Show the results of your mechanics from your calculator. For each section, give the

symbol and what the symbol means as well as the value.

4) State a Proper conclusion explaining what your data means.

Mention a specific dataset because analysis vary from each dataset to other, depending on the dataset one will decide what he is suspecting and what they know, what they are suspecting will be and what they know will be . Making data independent is impossible, what you get by sample suvey is your data and it could be independent or it could be dependent, depending on independence or dependency the analysis method differs.
