... • Example 1: When estimating the mean value from n numbers, each number is free to change regardless the values for the other numbers. Thus DF = n. • Example 2: When estimating the standard deviation from n numbers, we need the value x̅ which is the mean value. Once x̅ is fixed, there are only n-1 ...

... What If the $530 is an Over-Estimate or an Under-Estimate? The predicted bang-per-buck could actually be worse than your hurdle rate! There are many ways to do a risk analysis, and you’ll discuss them throughout the program. They all require that you know something about the uncertainty in numbers ...
