If the average weight was supposed to be 110 pounds, what is your percent error? Graphing: There will be many times throughout the semester when you will be graphing or looking at a graph and identifying the properties of the graph. Let's first start out with the basics. In a graph, there are 2 axes: the x-axis (horizontal axis) and the y-axis (vertical axis). If you were told to graph distance versus time, distance would be on the y-axis and time would be on the x-axis. It is usually in a "y vs. x" format. When graphing, follow these basic rules: 1. Determine which variable is on which axis. 2. Look at your data that you will be plotting and determine the range each axis will cover and make sure you draw your axes large enough to cover the range. Note: You do NOT have to scale the y-axis and x-axis the same, e.g. going from 0 to 10 to 20 on the y-axis and going from 0 to 5 to 10 to 15 on the x-axis is okay! 3. Label your graph and axes. A graph is usually labeled in the "Y vs. X" format. When labeling the axes, include the units used! 4. Plot your points. 5. Draw the line of best fit. THIS DOES NOT MEAN CONNECT THE DOTS! Only rarely will a graph need to have the data points connected by a jagged line. Usually, it is best to guess at a (straight) line that goes as near as possible to as many points as possible. THE ORIGIN IS NOT ALWAYS INCLUDED AS A POINT! And sometimes there will be a LOT of scatter and it might not be clear where a line should go. 6. Analyze your graph. Is there a trend? Would you be able to predict values not included in your graph? Okay, let's try a simple graph with numbers you already have. Look back at your table from #8. Let's make a plot of force versus acceleration. What will be your y-axis? What will be your x-axis? What are your ranges (min - max) for each axis? Make a labeled graph on the back page.

Let $U_1, U_2, \dots$ be independent uniform$(0, 1)$ random variables, and let $X$ have the distribution $P(X = x) = \frac{c}{x!}$, $x = 1, 2, \dots$, where $c = \frac{1}{(e - 1)}$. Find the distribution of $Z = \min\{U_1, \dots, U_X\}$. [Hint: The distribution of $Z | X = x$ is that of the first order statistic from a sample of size $x$.]
