FIRST COMPUTER SIMULATION ASSIGNMENT: CHAPTER 3 - Mean, standard deviation and histogram. When this assignment is completed please send it to my graduate assistant (email in Syllabus) via an email attachment. It will only be accepted in Word (.doc or .docx) format. That means if you do an assignment using Excel, you must copy and paste the Excel results into Word and save it as .doc (or .docx and NOT .xls or .xlsx). Simulation assignments and random numbers Throughout the term you will be asked to do several simulation assignments. To do those assignments you must generate random numbers in Excel. For example, using the Randbetween function. Each time Excel calculates the spreadsheet the random numbers change, so it may be frustrating to generate statistics based on those numbers. For example if you calculate the mean of the numbers you get a slightly different result each time you try it. To avoid this problem I suggest that after you generate the random numbers the first time, copy them (i.e., highlight them, right click and choose copy) and then paste them to another part of the spreadsheet by using the PASTE SPECIAL option. In that option, choose \"values\" and then \"ok.\" If anyone has a better way of doing this please let me know (for extra credit, of course). This assignment is a warm-up for all the subsequent simulations. Imagine you have a miniature roulette wheel where the possible outcomes are 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. Thus there are 10 possibilities and each has a 1/10 chance of occurring. Suppose you spin the roulette wheel 100 times. The results could be something like this: 3, 6, 0,4, 4, 9, 2, 3 .... What do you suppose the average will be? Since the lowest number you can get is 0 and the highest is 9, the average should be very close to the middle, i.e., 4.5 (0+9)/2=4.5 What do you think the standard deviation will be? It is difficult to guess this result, but by a formula you will learn in chapter 5 it should be 2.87. What do you think a histogram of these results will look like? Since each number (0-9) should show up as often as any other, the histogram should be \"uniform\" with no pronounced bump. There are 7 parts to this assignment. Please label them in your WORD DOC report (NOT EXCEL file) to me as Part 1, Part 2, etc. Part 1: In Excel there is a function which generates random integers between any two points. If you type into the A1 cell the Excel formula (by using \"=\") Randbetween(0,9) the computer will fill that cell with a 0 or 1 or 2...or 9 with 1/10 probability. By copying (by dragging on the corner of the cell) that formula into the cells A2, A3, A4...A100 you will get a column of random numbers that look like, for example: 3, 4, 9, 6, 6, 0, 5...etc. Show me that list of numbers. Part 2: Have Excel calculate the mean or average of this column of numbers Part 3: Have Excel calculate the standard deviation of this column of numbers Part 4: Have Excel produce a histogram of this column, using the 10 intervals: 0-1, 1-2, ...8-9 Part 5: Comment on your results parts 2, 3 and 4. Did the three results look as expected? Part 6: Redo parts 2, 3, and 4 but this time use 1000 spins of the roulette wheel. (I.e, copy the Randbetween formula1000 times.) Part 7: Comment on how and WHY your results in parts 2, 3 and 4 differ from those in part 6. Please be explicit about why you would expect this. Make sure to label each section Part 1, Part 2 ..., Part 7
