For this last question, let's see how well you can follow a recipe. Now, you do not have to understand where the recipe comes from, that is not what is being asked here. The goal is simply to following a scripted set of mathematical instructions to generate a result? How does that sound? The purpose of the following instruction is to enable you to calculate the uncertainty in the average of a set of values that contain random uncertainty. You will learn much more about the context in Part $2$ of this lab, however for now, do not bother yourself with the details. You will perform or follow this same recipe later in the lab when analyzing "small data sets". Your data set to work here is: $\{4,4\mathrm{.}9,6\mathrm{.}5,11\mathrm{.}2,1\mathrm{.}8\}$

Beginning at step $(2)$ in the table below, following steps $(2)-(4)$ to compute the uncertainty in the average $($Jargon Alert: The average and the mean represent the same quantity $-$ they're the same thing!$).$ Give your answer to one decimal place
