Our Chapter Eight project was a problem given to us by Mrs.Lewis, which we had to do a series of equations for. Katie and I first started by listing the main items in our equations, which were the: Sample Size, Sample Mean, Sample Standard Deviation, and Degrees of Freedom. We then had to calculate a series of interval based on 90%, 95%, and 99%, below those answers are explanations of how we got them. Part Two of our project was explaining more answers and giving insight on our project. Below is the table from which we received our data from (in thousands of dollars per employee).
